"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.

"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.

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.
