Significant improvement in acceleration at anyany speed. I upgrade all my vehicles with k&n cold air intakes.

I put this on my 2005 CheVy Silverado 4x4 Z71 step side or style side truck. 5.3 liter V8 automatic. I already had the magna flow dual exhaust on it. It sounds nice and no doubt adds horsepower. I have not driven it enough or far enough to determine if it improves m.p.g. any. Oh my son installed it on a freezing cold day outside quite easily

My truck runs on CNG or gasoline. When running on the CNG it is very temperamental with its need for enough oxygen. Even a slightly dirty air filter will make it run bad at higher RPM's. This COI definitely took care of that issue and I can feel a slight difference in power as well. (its not so noticeable when running on gasoline) It did definitely give it a cool new sound. (especially combined with my aftermarket exhaust)
