Wow....that's pretty good....not many people feel 1hp. LOL....are you serious? You sound like a ricer.hotmustang331 said:K&N gained 1RWHP on an 01 bullitt GT.Heck I felt the power gain from my K&N, not huge but it was there and kinda changed the sound of the engine and exhaust.



. Anyways I am pretty in tune with my car and know how it runs.That K&N also gave 3-4LB-FT, torque is what you feel, so I say that that is enough to be felt, and it was a combination of that and the much better throttle response that I felt.WOT was also slighly faster and seemed to run harder.
