    • Easy to install. Better mileage. Better performance
Style: 50 State Legal
I was very skeptical about this, however after a friend installed the same intake on his truck, I thought I'd give it a try. Mileage improved about 5% and the extra power when I tow my 5th wheel trailer was noticeable. Great design. I'm very happy with this addition to my truck!

    • Would recommend.
Style: 50 State Legal
Love this intake. Not super difficult to install. Took about 45 min. Noticeably increased the the sound of the engine, you can actually hear it sucking air and has a much throatier sound. The only thing I didn't like about this product is the rubber connector where the intake connects to the throtal body. After driving about 1000 miles with no problem it popped off and I was sucking air directly into the throtal body. It caused my engine light to come on due to the MAF not getting any readings. I fixed the problem and and after about a day the engine light turned back off. Other than the I would recommend any of my friends to get one. It also increased my highway mpg by about 1. I'm currently getting about 14.5 ... show more

Can hear the throttle body sucking in the air. Compliments the Gibson headers and Borla cat back exhaust on my 03 Chevy Silverado 2500HD. Noticed right away the ease of putting foot on pedal as my engine really breathes great now. Also opted to buy dry charger pre filter to protect filter from moisture and filter itself from ever having to clean debris out of crevices. Water beads up and just rolls off after droplets hit dry pre filter covering. Sounds like 8.1 big block in a way as it sucks in now much better. Had a drop in K&N filter before installing the intake kit and still noticed how much better air flow is now. You don't need to trim any fan shroud. Take off the Vortec cover above engine and slowly work on the tube to the throttle body. It will go on and give you a finger and half clearance from radiator fan. Just have to have a little patience. ... show more

    • Sent me bolts and nuts with ruined threads out of the lackage
Style: Metal
Still made it work but it’s all flappy and loose because of cheap hardware that’s ruined out of the package The bolts that mount to the air filter adapter don’t even screw into the adapter very poor quality hardware

    • If you know, you know.
Style: 50 State Legal
Most will say this isn’t worth the $. And I know from personal experience this is true, MOST the time. Including the 5.3’s. However on the 6.0 Vortec motors, this is a must for those of us trying to get any mpg gains, while giving a little support to the tuner especially when leveled/lifted with larger tires. Definite increase in throttle response, and obviously sound when in the pedal. But I’ve also seen about a 1mpg gain, prior to the tune, and closer to 3 mpg’s with the tuner. Still running the stock exhaust. Most noticeable gain though is the difference in power felt through the rpm’s. It definitely helps uncork the the air flow. Plus it’ll pay for itself within a year of driving in mpg savings. ... show more
