I have had an AEM cold air intake on my 2001 Eclipse GT for many many years, and it has worked well. While checking on a check engine light I noticed that one of the couplers had broken on the intake. I found AEM's website which was quite useful but due to the fact that I wasn't absolutely sure about the diameters I was measuring, I decided to ask for some help. I used the live help feature, and Kasia answered. She was extremely helpful and professional as well. After showing her a picture of my intake with the broken hose coupler she was able to pinpoint the part and send me a new one. The kicker was that it is still under warranty! I thought I would have to pay for the part. AEM's service and warranty cannot be beaten anywhere. I would definitely buy another for another car in the future. I also like the fact that the intake is CARB legal as well, which makes it a no brainer for someone like me who likes to install something and forget it. Thanks again, AEM!

I tried to find this item locally but could not. I am happy to find this on your site. I found it by looking at the parts list for a complete cold air system that I already own. My part was 13 yrs old and worn out.
