Need more than a replacement filter, how about the ram air system? Could be worth 10-12 horsepower.

Re: K & N Filter - 33-2457
I'm tempted but given the fact the filter (mopar) is new I'm not sure there's much point. They have test data on the webpage but it doesn't compare to anything, so there's no tangible benefit? Other then being re-useable.

The same K & N Filter (33-2457) is also used for the 3.6L V6.

As for airflow improvement with the K&N filter, the only figures I have found are on the BWoody page for their new Hemi intake, where they saw about a 5 percent better air flow using the K & N filter. Something, but not near as good as BWoody's whole new intake.

Dont waste your money on the K&N filter. The real problem is with the stock airbox. I bought the K&N filter almost a month ago, and could hardly tell the difference after I installed it. In the past, K&N filters have done wonders, but I would seem that the WK2 OEM setup beyond help. After installing the bwoody intake however, I was impressed.
