Exclamation Re: Power mods for the I-5

Had some improvement in performance by adding S&B Filter replacing stock air filter. In addition cut a 3" hole and inserted a aluminum flex tube running out under thru front starboard wheelwell to hole in bumper as a natural ram with a common air conditioner filter.
My estimate 5-10% gain in torque and hp. Impact on warrentee after cutting hole in air plenum is unknown!
