"Really easy to put in very good price and looks great! The turbo whistle sounds really good now, it turns heads." —Daniel R from Chicopee, MA bought a Spectre Cold Air Intake for a 2003 GMC Sierra, 6.6L Duramax.

"Noticed some ganes. Check light is the problem. They say it should go out. Don't beleive them." —Cory S from Lake Dallas, TX bought a Jet Power-Flow Mass Air Sensor for a 2003 GMC Sierra, 4.8L V8, 8th digit of VIN = V.

"Really easy to put in very good price and looks great! The turbo whistle sounds really good now, it turns heads." —Daniel R from Chicopee, MA bought a Spectre Cold Air Intake for a 2003 GMC Sierra, 6.6L Duramax.

"At first i was skeptical about buying an intake that wasn't a big name brand and cost over three hundred bucks, but the spectre intake i got fits perfectly in my sierra an dworks great. There is a noticeable power increase and small gain in MPG's. My truck also has a deeper tone around 2000 rpms and up. It looks great and i would highly recommend it, especially if your on a budget." —Henry B from Lookout Mountain, TN bought a Spectre Cold Air Intake for a 2003 GMC Sierra, 5.3L V8.

"Not only does this look great under my hood, the throaty sound and power gains are impressive. I installed this along with a CTS Evolution tuner and the results are bad ass to say the least. Goos looks, good power and good value." —Dwaine H from Astoria, OR bought a Spectre Cold Air Intake for a 2003 GMC Sierra, 5.3L V8.

"my sierra hd is bad , my 6.0 is alot more tough now my k&n complements my series 40 flowmaster duals it screams with full throttle I don't see a big mpg improvement but i can't keep my foot out of the throttle. when i rev it i can here that K&N sucking air it is cool. and the stainless tube looks great!" —Michael L from Monroe, MI bought a K&N 77 Series Metal Intake Kit for a 2003 GMC Sierra.

"I bout this air filter for mine and my wifes truck n we both love the extra power we got from our chevy trucks and the look of it under the hood" —Shane L from Dover, DE bought a K&N 77 Series Metal Intake Kit for a 2003 GMC Sierra.

"Performance is good. Install could use some help. The rubber seal is fair and could be improved. The boot between the throttle body and intake needs to be deeper to insure no vacuum leak as it is not a snug fit and needs the clamps to secure the air leaks. A rubber boot with a bit more resilience would help insure against leaks as well I believe. I also would like to purchase a FIPK for my 2007 GMC Yukon with a 5.3 motor. Are they available yet? Please advise and thank you in advance. Best regards, Mike " —Mike A from Pleasanton, CA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 GMC Sierra.

"The Spectre Cold Air is an excellent value and I noticed a increase in excelleration from day one I have not check the fuel mileage.I would recommend this unit to everyone." —Rick C from Fairfield , OH bought a Spectre Cold Air Intake for a 2003 GMC Sierra, 4.8L V8.

"Besides the drastic increase in my trucks mpg and horse power, it saves me $30 a year on an air filter and it looks and sounds good." —Robert Y from Chandler, TX bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 GMC Sierra, 1500, light-duty, 4.3L V6.

"Very easy to install except for a typo on the hole diameter of the tube for the filter gauge. Took me about one and a half hours, and a couple of brews to install. Looks and sounds great and everyone wants to see/touch it. Now to get a tuner that will work with this and a 3" Magnaflow catback system. I recommend it for everyone..." —Martin H from San Antonio, TX bought an AEM Brute Force Air Intakes for a 2003 GMC Sierra, 1500, 5.3L V8.

Volant HV Cold Air Intake Replacement Filters with Donaldson PowerCore Filtration Technology

great product

The filter is an excellent product, but it did not fit as well as the original Power Core filter in my Volant filter box. Had to raise the box cover by 3/4 ". View more reviews...

Injen Replacement Air Intake Filters

Just what you need!

I bought this air filter and when I say it came in perfect condition, I mean it. It came spotless, with a nice stainless steel adjustable tie, and it fits very snug on the intake. It sounds so nice at wide open throttle as well, anyone looming to buy an air filter should consider buying it from INJEN View more reviews...
