Great deal, arrived damaged, but easily fixable.
If your AEM intake arrives damaged, you can easily fix it. Head to your local AutoZone and borrow the OEMTOOLS 2-1/8 in. to 3-7/8 in. Tailpipe Expander. Hand tighten the expander into the pipe and then use a ratchet to expand and round the pipe out. I had to readjust the expander a few times to get the pipe as round as possible. It isn’t perfect, but I couldn’t pass up on the deal I got if I returned the intake.

AEM makes installing a cold air intake easier said than done.
arrived damaged/bent, didn't align with screw on Honda Prelude 1999. AEM, please fix your product and the quality control.

Works great
The intake definitely helps get more air and especially feels more responsive in colder weather. The installation process was a hassle because the mount for the intake did not line up with the mount on the car. Otherwise this product works great.
