i have a foam air filter and i was wondering if it it was okay to use K&N air filter cleaning kit on it, i ask because i think k&n filters are paper filters correct me if im wrong. i have a weapon r cold air intake, and the only place to get their "Weapon R foam filter cleaner" is online on a website that seems a little sketchy.

Spindrift

you talkin about that plasticy(sp?) stuff with the holes in it?

i've used K&N a few times on my foam perrin filter with no problems.

Just rinse it out, wring it out, and let it dry for at least 6 hours before even thinknig about using it again.

I can't see having to use K&N oil on it...that oil is the active filtering agent on a K&N filter, because the "screen" alone on a K&N does nothing for cleaning the air coming in. A foamy will filter just fine by itslef, I'd imagine the oil would hamper air flow pretty bad and may even damage it?

i dont know about not oiling it because the weapon r cleaner has a reconditioning oil also, but the WR site says not to use any other cleaner, or it will void warranty.
yeah its the plasticy stuff with holes on it, not like a sponge foam.
also you cant dissconnect the foam from its housing because its all connected im pretty sure but ill double check

Spindrift

then yea what merf said should be fine, and of course youll void your warranty cuz youre not using their product.

Who the hell returns a filter anyway?

Yeah if it's the same damn thing as the K&N, then use it. I thought we were talking abotu sponge-like foam shit.

Do it to it.

You DO need to oil a foam filter, it's the same as a cotton element filter like a K&N. It really depends on whether you want your filter to act as a filter.. The oil is still responsible for trapping and holding dirt, without that the foam isn't going to do that great of a job. The K&N cotton filter kit oil should work fine on the foam, it's just a detergent/emulsifier solution and red high tack oil. I bought a Amsoil foam filter kit from a local dealer and it's pretty much identical to the K&N kits I've had in the past. The Amsoil stuff was cheap, I'll be buying that for ever after for my filter needs. The one nice thing about the K&N kit is aerosol oil, the Amsoil stuff is a little bottle so you can work it into the foam by hand.
