ok, just to get this out in the air and over with i just want to let everyone know that the evoheatshield is a great product. for those who might believe it doesn't add performance, i thought i was going to agree with u, but its not true. you do feel a little bit of difference (feels like u gained about 5-7 hp) as well as lower IAT tempature.

you can look at in one of two ways:

it is another product you can buy to gain more performance and lower temps.

or

it is like a 2.8 chip, it may help a little bit, but $70-100 for a gasket isn't worth it.
(im not trying to dis on the 2.8 guys with the sw, its just a good example )

I just put it on today and have enjoyed the product thus far!
