"This is an excellent product both for its appearence and performance. The only problem encounted was with the instalation, the bracket and nuts and bolts provided had the wrong size for attachment to the fender too small for the threading that already existed in the fender well. Unfortunately the bolt that came out of the factory air box was on a slide type bolt so it could not be used. I had to improvise and this added at least an hour or more to what would have been an easy install. This should be addressed with the future kits for the Hummer H3 ALPHA with the 5.3 V8." —Gerald L from Peabody, MA bought a Volant Cold Air Intakes for a 2008 Hummer H3, 5.3L V8.
"Installing the K&N intake kit only took about an hour to install. It adds sporty to the engine compartment. At idle it has the feel of power. This intake realy comes alive between 60 and 80 miles per hour. The eng runs cooler. Have not got any info on mileage at this time but working on it. Mike in TN." —Michael M from Antioch, TN bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2008 Hummer H3.
"The Typhoon was delivered quickly, easy to install, and is much more appealing than the stock system." —William N from Royse City , TX bought a K&N 69 Series Typhoon Intake Systems for a 2008 Hummer H3, 6.2L V8.
"After install, better throttle response, acceleration and have picked up 1.2 mpg. Not bad." —Roger A from San Angelo, TX bought a Volant Cold Air Intakes for a 2008 Hummer H3, 3.7L 5-cyl. engine.
"I installed the k&N cold air intake myself with the instructions provided, this was a simple installation that took aroun 45 minutes by the time I got the tools out and put everything away. I am very pleased with the performance of this product. The difference with the hp is obvious, I could tell first time I drove the car after I put the intake on." —Andrew M from Athens, OH bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2008 Hummer H3, 3.7L 5-cyl. engine.
"Great upgrade! I have a high flow exhaust and the two together work great. The increase in horse power and throttle response was well worth it. Gas milage increase was only about 1-2 mpg. The main thing Volant needs to upgrade is their directions for installation. A diagram only is not good enough. I have installed several cold air intakes in my other vehicles otherwise I would have had a tough time installing this system with the diagram only. Overall great product! If you have a H3 with a 5.3 liter motor it is well worth it. To my knowledge they are the first ones with a cold air intake system for this application. I have been checking for a year." —James C from Gillette, WY bought a Volant Cold Air Intakes for a 2008 Hummer H3, 5.3L V8.
