"I noticed better pickup and power after install. Install was a breeze on my suburban, milage a wee bet better. The connector to the throttle body could be a little longer." —Kim A from Clayton, CA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Chevy Suburban.
"This system was easy to install. My main motivation was gas mileage and not extra passing lane power. I have read reviews making claims of 2-4 mpg improvement. I found more like 1-2 mpg. If gas makes it back to $4/gallon it will pay for itself." —Ian M from Greenwood, IN bought an Airaid Intake System for a 2004 Chevy Suburban.
"I received my cold air intake in less than two days without paying for extra shipping. I couldn't believe how fast it got to me. Install was quick. It sounds amazing. I definitely feel a difference when I step on the petal." —Bart Y from Las Vegas, NV bought a Spectre Cold Air Intake for a 2004 Chevy Suburban.
"2004 1500 2wd chevy suburban 5.3L. Low end response seems to be better. Getting on the highway entrance ramp is OK. High end response, seems to respond quickly and accelerate quickly. I am Still working on the mileage. Evenly Mixed highway and city mileage 14-15. City 12-13. Highway 55-60 MPH 18-20 according to instant MPG on Burb computer display. As long as you don't get on it the mileage will be OK. Power seems inmproved overall sound level not to bad(strong when you get on it), especially when I was in the wilber cross parkway tunnell in New Haven, CT. I think I scared a few people and myself. I will be towing a new 30 ft KZ light weight travel trailer 5400 dry wt this summer and hope for improved power in the western states thru the rookie mountains. The Suburban is 295 HP stock and the Scepter may give me 310 HP. About the install, Do I reinstall the bottom support plate from the old in take????? Overall I am pleased the muscular sound, the mileage and especially the price with the online coupon compared tot he other brands. Good luck and buy it." —Lawrence M from Stratford, CT bought a Spectre Cold Air Intake for a 2004 Chevy Suburban.
"Definately increases the get up and go factor. Good sound when heavy on the throttle. Would recommend the cloth cover to keep filter cleaner. Not sure about milage gain or loss." —Russ C from Steamboat Springs, CO bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Chevy Suburban.
"The performance makes a difference in fuel consumption and horsepower" —James M from Monee, IL bought a K&N 77 Series Metal Intake Kit for a 2004 Chevy Suburban.
"You can definately feel the difference in acceleration. I also put on an AirRaid Throttle Body Spacer and a Flowmaster exhaust and got about 50 more miles out a tank of gas, so far. I just put a gas saver chip on, so we will see how much more I can get. I had to knotch the Fan Shroud and each Fan Blade to accommodate the T.B.S. and the K&N Air Intake. So if you are doing both, just be prepared to do a little extra cutting. No big deal. The whole thing took about 90 minutes. I strongly recommend this set up for those who want to see results without spending big money." —Chris P from Madera, CA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Chevy Suburban.
