I went with the TTP intake and agree with all that the aftermarket intakes sound great. Dont know if there was any increase in HP as I did not do a dyno run with only a change in intake. Even though it sounds faster, I suspect there was little or no change in performance with the mod. One thing that does really impress me is how quickly the oiled air filter gets black with brake dust from the front brakes. I would guess that only 500 miles or so, a cleaned, freshly oiled filter is pretty black. I cannt imagine that is just from the road, so I figure if must be from the brakes. Has anyone else checked their oil-based air filters after 500 miles or so?
