Ractive air filter?

I am planning on buying one of Ractives foam air filters (mushroom). How are the foam filters in general? With this filter does it have to be oiled? Can you use the foam oil that amsoil has? Any Info would be appreciated.. Thanks

Is it for a stock setup or a air intake system?

Its for a short ram. Where the new air cleaner would sit just above the old airbox inlet.

K&N... you won't regret it.


...speaking of wich i need to clean mine.
