Decided to clean my Throttle body, Dry flow Air filter and MAF sensor this weekend, and thought I'd share how i did it. I have a Corksport SRI but for different intakes, and the stock intake the same instruction applies.
What you'll need:
- MAF sensor cleaner
- Throttle Body cleaner
- clean rag/s
- 10mm socket for intake clamps (Corksport SRI)
- T15 Torx socket for MAF sensor
Here is what I used

And here is a picture of my engine bay. For reference (just cleaned it too :D)

Last night once i got home, i removed my air filter, and capped it with a rag and elastic bands. I did it at night because i wanted it to dry while i slept.

I didn't get a picture of what i used, but basically you need to buckets. One for the dirty water, and one for the clean water. Now this would be much easier in the summer since you could use your hose but you'll probably end up refilling the buckets at least one more time. You'll take your filter and put it in the water, but be sure to not let water get past the mouth of the filter and rotate and shake the filter for a little. Water will still flow through the filter but nothing to much. switch from the dirty bucket to the clean bucket. Empty the dirty bucket and refill with cleaner water. Repeat as many times as you'd like.
Let the filter sit until it is COMPLETLY dry. You don't need water going into the intake tract. If you are just cleaning the filter, make sure everything is reassembled and tight, and you are done.
Now onto the MAF sensor.
This is what mine looks like. Remember I have a 2012 Skyactiv. Your sensor may look different, but they are all the same really.

You will get to this by unplugging the harness from the sensor by pinching the connector, and lightly wiggling/pulling it loose. Then using the Torx screw mentioned above, unscrew the MAF sensor from the MAF housing (black piece on my intake) and try and be gentle with it.
When looking at the picture, you will see a small resistor. You will be spraying that with the MAF cleaner. There is also a opening on the bottom and the right side where you will also spray with the cleaner.
Once you've sprayed it, set it off to the side and let it dry. It evaporates quick but 5-10 minutes to be safe. Now, onto the Throttle body.
I removed the whole intake setup, and this is what i saw

Looks pretty clean if you ask me
I tried to get a picture of the inside, but that was SO hard. Ill update once I buy a USB Endoscope

Spray the throttle body's butterfly (the part the opens and closes) as well as the insides as good as you can.
Let it sit for about 30 seconds and grab your rag. If you wanted, and could hold the butterfly open you could use a toothbrush and scrub a little better, but when holding it with your finger, you just gotta stick your finger with the rag in there. Here is what i got from that

In the first picture, the glob at the top and on the bottom of the second pic, has almost thick little pieces. Could just be from moving the rag around while i tried to clean it. I tried to get a better look into the Intake manifold, and i thought i could see some shiny liquid but can not confirm what it is.
Once you've finished up with that, wipe up the area, and reinstall everything, and make sure everything is tight and that you aren't missing anything. With the MAF sensor, it doesn't take much on the bolts to make them tight. Than make sure everything is tight again, you don't want a leak. If everything checks out, start the car up and see how it drives. My car had a little trouble starting at first, which I'm assuming happened because i was opening the butterfly when cleaning it.
The car feel much better, and seems to pull better and sound better too.
I hope this helps a few of you guys.
