i just bought a k-n- air fliter do i need a jet kit for it, all i have is a slip on, not racing, just casual driving

 

for casual driving i dont thing that u will need some jet kit

 

Your probably goin to need to re jet it. The aftermarket filters let in to much air. If you dont it'll run like crap

I personally recommend you stick with the OEM type paper filter, unless you're ready to do a lot of work to make it run right with the K&N.

 

I agree with staying with the paper. What's the point of putting on the k-n besides telling all your biker buds that you have a cool filter
