Aftermarket Air Flter Question

[dj147champ]

Is there a big difference between a K & N, MWR, or BMC air filters ?

No, All are close to the same. Race versions are thinner and usually not recommend for street use. I went with K&N's because they're cheaper and easier to get.

The stocker flows better than some and good enough for a large flow pipe.

There's the answer the OP needs to listen to.

No way the stock filter flows more air than the aftermarket.
Where's the proof to this org rumor?

stock does not flow better than a BMC.People makes these claims because they over oiled theyre k&ns or BMC filters.I noticed a huge difference in response after putting in a BMC and my stocker was almost new and clean.

+1, I won't claim any really noticeable power increase on my bike. But with my K&N and BMC Race I noticed a nice improvement in off idle throttle response.
The over oiling is a good point too.
