Somthing else to keep in mind about K&N's, they do provide more power, but at a cost...more flow means less filtration. I recently added a foam wrap to my K&N to provide better filtration after I sent an oil sample in for analysis and found unacceptable amounts of dirt in the oil causing high wear, I will see if the wrap works on my next sample...if not I will switch to a foam filter, to me it is just not worth the extra HP.
