Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable, reusable and easy to install with tools commonly available.

I had been reviewing K & N as well as Airaid air intakes for my H2 Hummer. I think they both make great products, but with Amazon's low price on K & N I decided to spend the extra $20.00 and get the K & N system.Ebay was the cheapest I had found with until I came to Amazon and they had the same price and I knew who I was buying from, so I ordered it.It installed quickly (about 90 min.) and the system runs beautifully. The sound was actually pretty mellow overall. It seems quieter on takeoff, but when you step on it you can hear it. You can also hear some noise from the passenger side after you install. Mostly some mild inhale/sucking sounds but nothing you even notice with the radio on.So far the initial benefits are more throttle response and it looks like I am getting about 1 mpg more than before. Not a lot, but for a Hummer that is about a 10% increase :-)I am very pleased over all. Also wanted to mention that I owned an Airaid system last year with my Ford pickup with a 4.7 Triton and it was much louder than the K & N. Quiet works better for me.I also want to commend Amazon on the amazing service they provide with the Prime membership. I ordered this system on Thursday afternoon wanting to have it on Friday so I could toy with it on the weekend. It cost me $3.99 to have this large box sent overnight to my house and I had it on Friday.Prime memberships are worth their weight in gold for frequent Amazon shoppers IMO.
