So I was planning to purchase a CPe TMIC for my 2010 Speed 3. I originally chose this over the Corksport TMIC as the CPe had a core size of 3.25" and the CS had a 3" core size, and I figured it would cool a bit better.
However, now I find out CPe is back ordered(on many items) as they are moving to a new production facility.

I don't really want to wait for the CPe TMIC as it could be two weeks or two months, pending CPe resuming production.

Leaves me with two options
1)Go with the corksport TMIC - is the .25" core size going to make a difference ?
2)Spend ~$600 instead of ~$400 and buy the ETS TMIC - not ideal, but if it will make a significant difference I would consider.

Thoughts ?
