"I installed the Helix Power Tower to my throttle body first, drove around two days. Ehh, o.k. without the K+N cold air intake.Gained a little. Then the K+N intake ,and with both of them on my 2002 GMC Envoy what a big difference! Highly recommend to anyone. Easy bolt on power 30min.max. Sounds good too when you need to get around all the tourists." —Kevin M from Wilmington, NC bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2002 GMC Envoy.

"I recently purchased a Travel Trailer. My 2002 Envoy 4.2 was pretty maxed out for towing. A friend told me about the K & N kit. I thought what the heck, try it. Boy was he right.I now have a big increase in Horsepower as well as an increase in Fuel economy. When running at or near the speed limit and it kicks in, it is like the Supercharger on my Grand Prix. Love it!!" —Denny B from Carrollton, KY bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2002 GMC Envoy.
