Cold air intake on automatic??

[ukr boy]

Hi there, it may sound stupid, but does it matter what kind of tranny you have when installing Cold air intake?
Thanks

[Nick]

i don't think so, i say go for it! you know you want it =]

[S.F.W.]

I run a CAI and have an Automatic transmission

[sauga_kid]

+1 I have a CAI and auto as well

[p-o-g-i]

+2 Automatic and proud of it.... (just don't tell anyone)... hahaha

[3GFX]

+1....performance parts on an AUTO don't matter. You can do many things the same as with a manual.

[She_Prime]

Hmm that's good to know. The boyfriend wants to install a CAI on my Auto 3. Now I don't have to look at him all crazy like.

Uhh...

[She_Prime]

Uhh...

What? Like the others I didn't think a CAI would make much difference on an automatic.

But people said it's good. So I'll let him do it.

[matt9]

I thought you already had a bunch of mods to worry about :P

[Nova 3 GT]

I have one too :) Instant torque boost on cooler days :bana

[fini]

it definitely won't be as effective as a manual transmission. by the time you get into a range that will start to see benefit from the CAI, the car will change gears on you. even with the tiptronic, it's pretty limited.

not being able to manipulate when and where you change gears will be the limiting factor on this kind of mod.

at least that's what i think....

but my motto is do what makes you happy :)

[x_o_k_x]

Auto or manual doesnt matter, almost all mods you can do for manual can be done in auto. Besides you might not even notice the difference in HP, but only the sound...

[ukr boy]

Thanks a lot everybody!! I just saw one for $150, BTW is it a good price for used intake?
and does anybody know how much would installation cost and how complicated is it?
Thanks

The PRM CAI/SRI lifts both the torque and hp curves right across the RPM range, so it shouldn't be affected by the automatic... in fact, it was dyno'd on an automatic....

I wasn't commenting on whether or not one can install the mod. I was just making the comment about relative usefulness.

I really don't trust the dyno results because I don't know how they were run. For example. 10 whp gain on the fujuta ? I think not. I don't think our stock airbox is that bad. But let's not get into that debate.

I still say people should do what they like because its all our own individual decisions

?? when you floor an auto it shifts at redline, when you are drag racing a mz3 MT, most will shift at redline also. Both tranny will use whole powerband when gunning it from a stop.

i admit that my driving time with an AT MZ3 is limited, but when i floored it. it never got up to redline.

Then you didn't floor it hard enough XD

Not to say I do it ALL the time, but there have been times I needed to floor it when driving and have hit redline...(mostly the on ramp to the highway)

you get more power on colder days no matter what kind of intake you have

But let's not get into that debate. I don't see how the cold air intake is more/less useful with respect to the transmission in this case. 10 HP gain from an intake is pretty decent.
2.3L w/ 160hp... the engine isn't tapped out; its not hard to believe. You should see the gain on the Mazda 6 V6 (1st gen Mazda 6; not 626, the 6).

When in tiptronic mode, the gears will not shift for you in a Mazda.

edit: CAI on an auto is done by many members here. Although, I personally avoid power enhancing modifications to the car because of my experience with Mazda Auto Transmissions and insurance.

[1flycdnM3]

I have installed over 500 intakes in my life and clearly done it on Auto/Manual so i know the gains and so on. Don't expect to be "launched out of your seat" or anything but the sound and the "fun factor" are a major plus. Also, dont have to change your filter (thus saving money in the longrun if you plan to keep your car a while). Most filters last atleast 2-3 years and others (such as K&N) can be cleaned/re-used for a LIFETIME.

Hmm that's good to know. The boyfriend wants to install a CAI on my Auto 3. Now I don't have to look at him all crazy like.

Dont let him do it!!!!! He will use Home Depot parts and cut a hole in your airbox, and keep the CAI for himself!!! LOL!! (oops.... I said that out tooo loud)

I'm kidding... Too early to drink?

Just a bit Ryan. Just a bit. ;)

Well he DID botch the one going into Alan's 3. So maybe you're on to something. Hmm...

We shall see how the winter progresses and whether or not I decide to keep him around ;). Maybe if I don't then I'll still get a CAI.

It's a win win situation :D

[RedRaptor]

I have the MS CAI on my auto. I've had it for 2 years now. Don't expect much out of it other than the fun and sound factor. :)

[Stretch]

So how hard would it be to make one for our cars? By the looks of that $150 kit in the first page, it shouldn't be hard at all.
eric

[dentinger]

just do it.

you'll gain like, .5 hp, but you'll get more miles to the tank.
with my catback, and intake, i gained 100 km's/tank... for the first year.
now its back to normal....

[1flycdnM3]

it sounds cool, improves gas mileage (slightly) and gives you better throttle response (always a good thing) so for the $150-$300 price tag it is WELL WORTH IT!

soooo... do it! :)

[ukr boy]

Thanks a lot everybody! I think I'll do it! I just have to find out how expensive is it to install! Do you think I should do it at dealership or regular mechanic will work?(would it affect the warranty?)

regular mechanic, unless you get the Jetstream intake, which you can do yourself in about 30 minutes.

[Donutz]

Like $40 or less. I think I paid $100 total for CAI and CBE install.

[Nick]

should give it a shot yourself, it's a fun little project!

[BenChan]

DO IT ! i have an auto mazda3 hatch with CAI. Gives a nice sound and you can feel SOME what of a difference when you add it on. all in total i think you should DO IT !!!

[Ogata]

if you do a CAI...you will have to change your exhaust too no? The more air you get in..shouldn't the hold be bigger for the air / gas to come out?

[Nova 3 GT]

if you do a CAI...you will have to change your exhaust too no? The more air you get in..shouldn't the hold be bigger for the air / gas to come out?

That would be the ideal but it depends if the guy have some cash left in his or her pocket. But on the other hand, I guess that the proverb "What goes in must come out" applies here. :chuckle

[-RJ3-]

One thing I noticed.... If you dont have an upgraded exhaust sytem and have your CAI you will sometimes hear a loud pop sound around the intake when giving some gas...

Unsure if its related, but I changed my exhaust system and no popping sound near the CAI you now hear a bit of backfire in the exhaust...

[Ogata]

agreed the more air you swallow the more it needs to fart out so i don't know if that is a good thing or a bad thing even if you know how to control...I'm still debating if I want to add a CAI because I don't want to add an exhaust because I like the sound of stock aka quiet.

[phoenix_bladen]

i don't see anything wrong with a CAI in an automatic

however for a cat back exhaust i would prefer no exhaust or a very low sounding one

since when the auto shifts by itself it sounds very weird...... with the exhaust sounds...

I noticed this too! Especially in the winter months my exhaust pops LOUD sometimes! I love it! sometimes sit there in idle and give it a few little revs and then BANG! hahahaha! Neighbours dog loves it too :)

When it's cold like -25 or below, instead of doing the usual CAI sound (sucking air sound), it does a slight spooling sound almost as if I have a turbo :chuckle

[Veritaz]

Isn't that bad for the engine? Or does it have no effect?


Exhaust backfire is usually caused by unburnt fuel detonating in the hot catalytic convertor. It often happens with a less restrictive exhaust systems when climbing revs under almost no load and when decelerating when the engine does not cut fuel right when the throttle is closed. Not really bad for the engine but it can cause premature wear to the cat.

My car backfires like a madman on a daily basis as the Haltech isnt tuned to cut fuel on decel. When I am slowing down with the clutch not depressed it is a constant pop...pop...pop pop BANG!... pop pop pop BANG!

lol

[Ogata]

any of those CAI's on auto have a bigger catback with resonators on? I believe noone has answered my question if you need to change it since you are sucking more air in...then shouldn't you have a bigger hole for it to fart out?

[x_o_k_x]

No its not required, but you do gain more horsepower if you add full exhaust on top of CAI.
Only if you turbo your car then its required to properly run, CAI not so much

Can you explain the mech's around it? If you suck more in...then more air needs to come out otherwise there will be combustion no? I'm no science or mechanic myself but it doesn't make sense...I was planning to do a CAI but then the exhaust came to mine and I have yet to find one I like thats as quiet as stock.

[STeeLy]

I don't think you will ever find an aftermarket exhaust as quiet as a stock one...

Couldn't have said it better myself, although I am not 100% sure about how long it would take to actually burn out the CAT (i have been doing this a long time and no issues), but im aware this is a possibility and would honestly use this as a good excuse to purchase a hi-flow CAT lol

[1flycdnM3]

This question is a tireless one to answer, but the short answer is "you are correct, good sir" so if you are looking at having an exhaust quieter than stock, then don't get one!

[Veritaz]

The best explaination would be the over engineering of the stock exhaust. The exhaust on the vehicle is MORE then sufficient for the stock airbox, so when you increase the air intake density the stock exhaust would STILL be sufficient, up to a point. Even with a turbo kit running you can use a stock exhaust up to about 225whp.

Furthermore a cold air intake doesnt so much "suck more air in". It allows the engine to get the same ammount of air it needs with more ease and also delivers colder, slightly more dense air, aloowing for better combustion and faster throttle response. A turbo sucks more air in and a cai just makes it easier to get air, If you sucked a whole lot more air in with a CAI you would need to retune your injectore duty cycle to prevent spiking lean.

long story short a CAI will give u small hp gains and an exhaust is not needed to compliment it. You will however see more performance out of a CAI with a more free flowing exhaust due to the easier movment of air through the entire induction/combustion system.

Yeah I got a high flow cat in my 3" turboback system. It doesnt so much burn out the cat as gum it up with oodles of crap.

I don't want to :TJ but... which aftermarket exhaust is good to go with a CAI? Any CBE or is a Hi-flow needed?

[Veritaz]

To be honest most people are more concerned about sound then actual gains from an exhaust system these days. Really though any proper engineered exhaust system(mandrel bent with minimum bend radius' taken into effect) with larger then stock pipes would net you some gain from both the exhaust and CAI. Hi-flow is really a marketing catch phrase rather then an actual benchmark, the term hi flow is usually used to say slightly easier flowing then stock lol.

[Veritaz]

it should be said aswell though that without a turbo bolted on the exhaust manifold that a extreemly free flowing exhaust system could definatly cause some pre mature wear on your valve springs. Unless turbo You definatly still want some backpressure in the system so a basic CBE would probably be best to compliment a CAI.

[STeeLy]

Definitely not going to turbo my car...

[jova87]

i got a magnaflow cat back, and a injen CAI.. the exhaust backfire, earlier mentioned, is that the popping sound it makes at low rpms when going 2nd to 1st.
i also have an auto.

also after a bit of driving, i notice a heavy drone sound from the exhaust when cruising at about 80, the exhaust becomes really loud and annoying. happen to others with auto+exhaust..

this is one reason i don't have an exhaust yet, on they highway its annoying. more so on auto tho. im still gonna have to get one next year tho.

Unless you get a quieter CBE like a 5Zigen, any aftermarket CBE without things like resonators added to them, are all pretty loud and drone on the highway in a NA aspirated MZ3. They will drone a little more in an auto, but they still drone even with a 5spd.

this is what i hear, nothing really noticable. i could be wrong tho.

[Zoom Zoom Boy]

Does a SRI or CAI improve fuel efficiency??

Yes, but not by a huge amount. However, it does improve fuel efficiency nontheless.

To give you an example, I am saving between 0.5 to 1.0 litres of fuel per 100km of driving in my MS3 since installing a COBB SF Intake. On a tank of gas, this amounts to a savings of about 2.0 - 4.0 litres of fuel which eqautes to about 20-40km of extra driving distance based on my 'average and historical' fuel consumption and mileage.

Don't waste ur money on getting a CAI on a 2.0L or 2.3L engine car.
You are going to think it the throttle response is better, and maybe even your car seem more powerful, but ur not gaining anything.

[trademark83]

It sounds louder, making you think there is a difference in throttle response..but its just noise. 10HP from 150$? Besides, if you really want a faster car,buy a faster car in first place. Tryin to push a couple more hp out of a small engine is a waste of money and just screws up ur car in long run.

3 posts in 7 minutes and a lot of short and flippant posts of late. So, save us the suspense and let us know what you have to sell once you get your post count to 50...

Also, you will get small gains from an SRI or CAI alone and it makes the engine breather easier and better. Yes, throttle response is improved and in cold weather, you will most certainly notice an improvement gain over stock. Less so in the summer. Also, unless you hydrolock, having a CAI or SRI is actually better for the longevity of your engine, not worse.

I'm not searching for your posts. They are hard to miss since you are posting a few one liner comments in a lot of threads without actually contributing anything, so, I tend to see them since there are so many of them. This is usually symptomatic of someone who wants to get to the 50 post count so they can flog stuff on here.

Here is the basis at a really high-level. Engine breathes better and easier which means the engine has to work less to provide a better air to fuel ratio mixture. Engine working harder, bad... Engine working less and breathing better, good...

When he asked you to prove what you are saying about the actual topic, you change the subject into something else or just say something simple. How are we to take you seriously when you do that? Also the first thing you say when you come into this thread is to basically insult people who want to get a CAI or SRI but don't really offer any substantial advice/info on why they shouldn't other than you wouldn't?

The premise of his statement of me trying to get 50 posts so I can sell something is laughable. I don't know what the visitor count of this site is but whatever it is, I am sure it's insignificant relative to craigslist, kijiji or rfd. If I wanted to sell something, I would go to those places. I'm sure most people who surf this website also go on those sites.

I am on here like anyone else, talk about mazda3's. I've met Joe from MOT and Dan (Mcguyver) on two different occasions, one for parts and the other for car service.
