I recently purchased an FIPK for my 2005 BMW 325i from AutoAnything and I also got one of these filter covers. You can call it a pre-filter for sure because it does add an extra layer of protection. The material is excellent and this is a must have item if you have one of these filters in your car. The only thing is it is a bit pricey at almost $30, now if it was $10-$15 I think it would be a lot more reasonable. Personally I wouldn't think about having a cold air exhaust without one of these!!

I highly recommend this K&N filter wrap. It protects from water and stops dirt and some dust. Therefore air filter life is extended and filtration increased. I use it with all my cars that have cone air filters. Worth every penny.
