I installed the intake in a reasonable time and I love the sound when you push on the gas. Looks good in the engine bay. I believe I am getting about 2 more mpg than before.

Very satisfied with the purchase. The performance has improved and the sound the car now makes is awesome. Their was a part missing, but they promptly send the missing part with no hassle. They say it can be installed in one hour, but it took me two hours. Having done one now, I could do the next one in about one hour. Zoom Zoom

Beautiful intake, but....

I love everything about the AEM intake, except for one important thing. It's attractive and precisely made and installation is a breeze. Declutters the engine bay. The only thing is, at least in summer weather, it heat soaks so much that the air box and intake tube (both aluminum) become too hot to touch after only a few minutes. I don't know that it makes much difference as the air is only passing through for a very short time, but it doesn't make intake air colder than stock that I can tell.
