wow...you can feel a difference?
lol, same thing I was thinkinglol i just find it funny he can notice a big diference
Injen Pre-Filter = Windryflow AEM > k&n
K&N filters are garbage and if you search bobistheoilguy.com in the forums, you'll see why.
I dont know if it's only 1or 2 hp,but i can sur feel the difference,if you go from a dirty filter to a Dryflow you might not feel a difference,but i went from a clean stock filter to Dryflow to k&N and i feelt like the Dryflow made me lose more than 1 or 2 hp,even the hissing sound the engine make when you turn it off was muffled by the thick material that AEM usesDude you are talking 1 or 2hp here. How can you notice that difference?
