    K&N X-Treme Motocross air filter vs. Foam filter?

    The foam filter is $30
    Amazon.com: Twin Air 154112X Pre-Oiled Dual Foam Air Filter: Automotive

    The K&N Filter is ~$100
    Amazon.com: K&N KT-5201 KTM X-Stream Motocross Air Filter: Automotive

    So for $70, does anybody know if the K&N Kit is actually less restrictive than the foam option?

    Since it's for a motard, I don't think dust capacity is really that important.

    I'd just clean and re-oil the filter that is in there (preferably trackside with fork oil and a turkey baster), but it's got a bunch of fiberglass on it from a leaky exhaust can that I plan to replace so I'd rather just replace the filter altogether.

    You can get a NoToil pre-oiled one for $30 or less if you REALLY wanna go the easy route.

    Personally I'm not a fan of K&Ns or oiled paper in general.

    That is the pre-oiled foam filter.

    Any specifics on why you don't like the paper filters?

    They let more dirt past, and they don't flow anywhere near as well once you clean them and re-oil.
