I didn't feel any noticeable power increase. Quicker throttle response and a nicer inlet sound were present. You shouldn't expect much from something that dyno's 1-3 hp on everage. I put a K&N on my old '93 notch and removed the air silencer. There was a noticeable difference on that vehicle but not really on the bullitt. Either way, I'd go for it, it helps later with more inlet mods, like....extrude honing!
