Not sure which 2008 GMC Sierra Cold Air Intakes are right for you? We have over 18563 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"Looks good. Installed it along with a Helix throttle body spacer. Has more low end torque, but haven't driven it far enough for a fuel mileage check. Haven't heard much, if any, more whistling, etc., these mods are sometimes known for. The installation of both at the same time was very convenient, since removing the original intake is required for either.
Install was a tad tougher than K&N would suggest. Had to do some cutting, bending, and drilling to install the heat shield the filter sits in. Inner fender problem required cutting and bending, and the bottom of the heat shield required a 5/8" hole be drilled into the bottom of the air box on some trucks, like mine. At the very least, I have more torque, and hopefully, better gas mileage." —Thomas W from Hansville, WA bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2008 GMC Sierra.
"Did the job. Definately more juice! Better throttle response. Love the sound when you step on it, it also made the borla exhaust sound deeper." —Frank R from Pharr, TX bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2008 GMC Sierra, New body style, 1500, 5.3L V8.
"-Took me a while to fix it since it was my first time to get in the hood!
-Instructions where fine, but could've been better with clearer images.
-Wasn't 100% satisfied about the fixing, however gains made me forgive!
-Was doing 7.1s before. After was doing easy 6.8s
-Sound is fine as long I dont floor it, otherwise nothing much is noticeable!
-One thing though, more engine heat coming in than the stock one, so dont expect much in freq. stops & heavy traffic in summer
-Lost 0.5MPG in my first run, still watching though" —Mohammad B from Springfield Gardens, NY bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2008 GMC Sierra, New body style, 1500, 5.3L V8.
"easy to install cause I watched another brand put in the same truck. The instructions? Must have missed somethin in the expanded parts picture. It doesn't tell you to use some of the existing hardware. Over all, it did just what the doctor ordered. Go fast or save gas." —David K from Livermore, CA bought a Volant Cold Air Intakes for a 2008 GMC Sierra, 5.3L V8.
"Makes a difference! I noticed more horsepower as soon as it went on. I'm not sure about the mpgs yet as I have had a hard time not putting my foot into the gas pedal. The price through autoanything was cheaper by far than any other site or retailer that I have seen." —Chris B from Salem, OR bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2008 GMC Sierra, 5.7L Hemi .
"Good instructions although lacking regarding removal of several other bolts to allow extrication of the factory air box. One also needs seveal other tools includin 10 and 12mm sockets. Easy fit after removal and great finish. Immediate and noticable improvement in throttle responseand overall performance. Well worth the money. Sounds awesome and looks better. 2006 MITSUBISHI ECLIPSE 2.4L" —John K from Leesville, LA bought an Injen SP Series Cold Air Intake for a 2008 GMC Sierra, 2.4L 4-cyl. engine, automatic transmission.
"I installed this intake in about 35 minutes and was very impressed with the fit and quality of all the parts.When driving normal you don't even hear the intake and when at heavy throttle its sounds really good but not too loud.I noticed some more midrange power and fuel economy has increased by about 1-2 mpg.Very good product and couldn't beat the price from Auto Anything anywhere." —Dustin D from Winder, GA bought a Spectre Cold Air Intake for a 2008 GMC Sierra, 5.3L V8.
"The kit goes in flawlessly. It is harder to get the old stuff out than get the new stuff in!!" —Jason C from Bradford, IL bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2008 GMC Sierra.
"fit perfect. looks great. I can finally use my hypertech programs. I noticed the increase in power and response. I don'tdrive the truck much so exact number of mpg increase, but my guess is close to 3 mpg's with the programmer. the engine sounds mean under load. I am very happy with the purchase." —Kyle W from Rensselaer, IN bought a Spectre Cold Air Intake for a 2008 GMC Sierra.
"I ordered and installed the complete Airaid intake system plus the addition of the Poweraid throttle body spacer and there is a noticeable difference in power. I have not been able to get to accurate of a read on the gas mileage setting as with winter here the vehicle is warming up more than anything else. The installation was easy and took about 45 minutes with thoroughly reading the instructions (the instructions provided were great as these were definitely vehicle specific and were not confusing at all)" —Thomas M from Highland, MI bought an Airaid Intake System for a 2008 GMC Sierra.
"This CAI was very easy to install and only took around half an hour from start to finish. The fit is perfect in my Sierra 1500. I added this CAI along with a Gibson Super Truck exhaust on the same day and got substantial "seat of the pants" gains. The truck sounds and runs much better. Since I added both products at the same time I can't really say how much extra performance you will get with the intake alone but I highly recommend it especially with an exhaust upgrade." —Chad B from Fayetteville, NC bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2008 GMC Sierra.
