I have an '03 45, I have the oem k&n filter and the acceleration is smooth. my question is which will give you better performance the k&n or the weapon r pop charger.
 
k&n doesnt make a specific intake for the 35 or 45, just filters. dr.2k has the weapon r intake on his 45 though, check that out.

there are other brands out there that make an intake, such as LMS (rare) and JWT (not sure how many are available)

Negligible difference in performance if any. Mostly placebo effect on a butt dyno, lol. However, mileage seemed to have gotten a bit better possibly 0.5-1.0 miles/gl and sound is more aggressive with the weapon-R.
