Air Filter Question

[SANDFLEA85]

I run K&N...because my bike is mapped without a filter..bought it as a drag bike and most drag bikes dont run a filter since it restricts air,so its the closest thing to not haveing a filter as far as i know..

K&N it was in it when I bought it.

After my local shop tested a couple aftermarket filters on his flow bench and found that the stock filters flowed more air....STOCK.

If I ever went with something different it would be a BMC Race and that would be to have something I could reuse.

All I needed to know right there. Thanks for the input, folks!

If stock one is working leave it alone. Its cheaper anyway.

Stock can cost as much as a aftermarket. You have to consider youll only buy one k&n and a filter cleaning kit at $60 in the vehicles lifetime. Every replacment factory filter cost $30 and youll atleast use, say 6 of them.

as a counter... dyno'd (area under the curve) better with my BMC race over the OE  

 

I think the main reason I moved away from OE which is what I do with any engine is because it's reusable.

I'm going to give the Piper Cross Race filter a try.

BMC race here for street use only......I had it in my 02 busa & just recently but it in my 04...

Results at the above link.

BMC Race seems to work better than no filter. Especially between 4,000 and 9,000 RPM.

BMC Race and Pipercross seem to be really close. BMC Race is slightly better around 8,000 RPM

Both BMC Race and Pipercross work better than stock OEM filter.

All testing was completed within 45 minutes. 3 runs were given to each filter. The best run of all filters were used.

I def trust Ryans testing  

And that doesn't take into account the much sharper throttle response from the lower resistance of the free flowing filters when you crack the throttle. Those are just wide open full vacuum tests. Try one and you WILL feel a diff. And combine it with exhaust and pc/mapping and its even better
