"Installed this on my 03 Suburban and love it. Put it in with a Airaid Poweraid throttle body spacer. Took about an hour and a half and was super easy. Got it to hopefully boost the MPG's on the beast, but the extra horses are great too. Throttle response is greatly improved, sounds awesome, and it seems that she just runs a little smoother. Feels a little quicker too. We'll see about the MPG's." —Preston F from Amarillo, TX bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Suburban.
"This was my first time buying a CAI, but have had K&N filters in my other vehicles. Installation was very easy and the instructions were clear. It cleans up the engine compartment quite a bit over the factory intake. I love the sound you now hear under heavy acceleration and it's not noticeable under normal driving conditions, which is nice. I haven't check to see if there was an MPG increase or not. Overall very satisfied!" —John D from Wyoming, MI bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Suburban, 1500, 5.3L V8.
"easy to install great fit and quality. really opens up the engine compartment. very good air intake upon acceleration.good quality over paper filters.highly reccomend but dont expect miracales with just an air intake." —Stephen P from Bayville, NY bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Suburban, 1500, 5.3L V8.
"very easy to install and you can really feel and hear the extra ponies from the intake. mileage is better...when my wife drives." —Warren D from Corona, CA bought an AEM Brute Force Air Intakes for a 2003 Chevy Suburban.
"I can definitely tell a differnece with the K&N Cold air intake. It seems much stronger." —Joshua E from Wake Forest, NC bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Suburban, 1500, 5.3L V8.
"It doesn't feel like I have more power, but it does seem to come on smoother and there are no dead spots in the throttle. I'm not seeing any mpg improvement but my regular commute is in LA traffic either under 30mph or over 70mph, not exactly the gas mileage sweet spot on this truck. The stock intake tube has two HUGE sound-reduction chambers, so I do not doubt manufacturer claims that it flows much more air than stock. Unfortunately most of my driving conditions don't take advantage of that. I imagine much greater gains are possible when compounded with a programmer and/or exhaust upgrades. Installation instructions were clear, easy to follow, and the product fit and finish is better than stock. No complaints." —Ben R from Granada Hills, CA bought a Banks Ram-Air Intake for a 2003 Chevy Suburban.
"After having my k&n cold air intake installed in my 2003 chevy suburban, i immediately noticed better fuel mileage(1-2pmh)as well as response when i step on the accelerator. I would reccommend this product to others hoping to see better fuel mileage and performance." —Mark A T from Danville, IL bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Suburban, 1500, 5.3L V8.
