Great filter. Had one before on my car for 3yrs. Finally got around to getting a new one. After installing the new replacement filter I got better everything. Car felt way better, more power all around. And sounds great.

This filter is better than the gray filter that came with the CAI which began to fall apart at the top. The old gray filter is made of rubber around the top and bottom and started to crack and break apart. The replacement is better designed with a mesh around the filter and a hard plastic like material around the top and bottom. I definitely give this my full endorsement should last much longer than the other filter.

The AEM Dry Flow air filter is the only way to. Ever since I bought an AEM intake I was sold on the quality. Filtration seems to be superior after pulling the intake off & looking at how clean the inside of the pipe & throttle body still are after over a year of daily driving.
