"Lets my Envoy breathe when I'm towing my racecar to events. Obviously GMC restricted airflow by design but this K&N lets my Envoy take big gulps of air that it really needed to tow my load and it is very happy now!" —Rodney T from Spokane Valley, WA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 GMC Envoy, 4.2L 6-cyl. engine.
"Noticed increased power & fuel economy with the first tank of gasoline. Increase MPH by approximately 10% and power is there when needed for passing on the interstate." —Lawrence F from Montague, NJ bought a Volant Cold Air Intakes for a 2004 GMC Envoy.
"This intake for my Envoy is pretty sick! Makes the truck soundlike a muscle car its great! As for the horsepower, it gives it a little more of a push but not as much as i hoped for. Probably gives ya about 10 more horsepowere which will make me move more than usual but i was hoping for a little more. As for installation, impossible to do yourself unless your great with cars. I brought it to a place to install for it $40...I love the intake but for three hundred bills i was hoping for a little more!" —Alex M from Jackson, NJ bought a K&N 77 Series Metal Intake Kit for a 2004 GMC Envoy, 4.2L 6-cyl. engine.
"The FIPK Air Intake, coupled with my throttle body spacer, has been a treat. The sound that the intake makes is addictive and the increased aceleration is extremely noticeable. Went on a trip to Miami and the highway mileage was 21.5 mpg (previous average mpg on highway was 18.8), and that in itself made the purchase worthwhile. Installation wasn't difficult, but the intake comes totally disassembled (I wasn't expecting that.)" —Leonardo R from Maysville, NC bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 GMC Envoy.
"Love the way this CAI makes my 04 Envoy sound. Roars now (relatively speaking). Install was a little more complex than I'd like but not terrible. Had to drill a 1 1/4 inch hole for the air injection but all in all install was clean and easy. I had all the installation parts I needed in the kit.
Extremely happy with my purchase and the K&N 77's performance so far." —Thomas N E from West Haven, CT bought a K&N 77 Series Metal Intake Kit for a 2004 GMC Envoy, 4.2L 6-cyl. engine.
