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.

Small but worthwhile gain
By A. Kilger
I bought this product about a year ago from Amazon. I hooked it up in about an hour with few to no problems. I realize many of you don't like to read instructions, because neither do I, but I strongly recommend it in this case. If you don't follow them, you will miss important steps that are definitely needed to install the intake.There is no gain in gas mileage, so save your Benjamins if that's what you are looking for. As for horse power, I will say it makes a small difference, there is definitely performance to be had on the throttle response from the product.The most noticeable difference from this intake though is the sound. When you drive normally it will make no difference to the quietness of the vehicle. However, when you step on it a little more, or really floorboard it, it will be louder than your radio, that's for sure. It has a very distinct sound, and everyone that I know that has heard it really likes the sound it produces.I further recommend that you hollow the airbox and reattach it over the intake instead of the heat shield provided. It won't choke the intake and it will also help keep the air far cooler (which is the point of a cold air intake). If it sucks in too much hot air it will affect the timing and power.Great product, I give it 5 stars! I also prefer it over the metal intake of the same model because obviously plastic won't get as hot as metal, and help insulate the air.

You can feel the difference!!! Power for my 4.2 Chevy Trailblazer!
By Jet Lee
This will be my fourth K&N intake system for a car I own. I've always doubted all of them when purchasing, including this one. But they seem to always amaze me. The rush of power and the sound of cool forceful air screaming into the intake is phenomenal! I cannot help putting the pedal to the metal. Power can be felt in all RPM ranges, but when you floor it...man the power just climbs until the engine upshifts, then you do it all over again. I initially made my own intake system, but there were choke points and the K&N design just gets rid of all the restrictions while allowing big increase throughout the powerband. Amazing and quality product, I did not use the shroud included to protect the intake from engine heat as i've read it doesnt do a great job. I already fabricated my own shroud and it works great with this system. I felt the intake tube and filter after driving hard and it was even with the ambient temperature, so I did a decent job with keeping my cold air intake....cold. So I cannot comment on the the intake, but I am sure it keeps away engine heat somewhat. I recommend adding your own insulation to fully unlock your intake's potential. This totally woke up my straight six engine, along with my exhaust and engine tune. If you are thinking of buying...you wont regret it! You will only enjoy it.

My only concern is the heat shield.
By Gavin E. Birch
First off, this will fit 02-05 Chevrolet Trailblazers, despite the "Make sure it fits" tells you it won't. Installation was pretty easy, the only this I would recommend is purchasing a small hose clamp to add to the crankcase vent tube (one doesn't come with the kit). Sound is pretty low key unless you really stomp on it, then it becomes very noticeable, and will certainly drown out your radio.The heat shield is really bare bones, though, and this intake still gets hot to the touch with the heat shield in place. I will probably hollow out the stock airbox to insulate the filter better, as the point of a cold air intake is to, well, intake COLD air. Knocked two stars off the product for that.
