what filter and jet sysyem gives you the most horsepower increase?

 

The aftermarket filters all flow about the same, the best flow is with a clamp on system and a removed airbox lid (or no airbox at all if your riding conditions allow it). There's not much of a difference in jet kits, but in my opinion jet kits are a waste of money when you can go to a dealer and buy individual jets for a fraction of the cost.

 

I dig the K&N Filter and DynoJet kit for my Raptor, definately no complaints.
