To those that are want to get one:

I search the web to get the best price.
I have no connection to the company other than I bought a filter from them.
I paid the price on 4-28-99, it could have changed some.

Performance International   E-2475  K&N Air Filter  1   $27.42
Performance International   99-5050 K&N Service Kit 1   $8.95
