"This ia my first full K&N intake kit I have used, but not my first K&N. I have K&N filters in My Caravan, Grand AM GT, Mustang GT, those vehicles are just using the filter in the factory OEM box and they work great. I purchased the 77 series kit for my 2003 Trailblazer, it is the first of my vehicles that accepts a full intake kit. I must say it is a great improvement in response and acceleration, I can't say for sure if the gas mileage has improved, it seems to be the same, but have only checked it on 2 tanks of gas, plus I have been putting my foot into pedal testing its performance. My nephew has the same trailblazer and he drove mine the other day and was completely impressed, so as soon as he needs a new filter he will purchasing a 77 series for his trailblazer. So either way you go(full intake system, or just a K&N filter charger, you made a good move). Also this is the second K&N product I've purchased from Auto Anything and I must say as before it was painless and at the doorstep in 2 days. Hope this helps in making your decision on a purchase, rev'm up and have fun

Thanks Autoanything.com" —Gerald D from Corning, CA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Trailblazer, 4.2L 6-cyl. engine.
"The installation for the FIPK 57-3036 was fast and easy, the performance looks great, so far 3000 miles, the only complain is at some high rpm it gets a little loud." —Rene M from Mexico City, D.F. bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Trailblazer.
"I am no stranger to K&N products, I use them a great deal. Recently I put the system on my 03 Trailblazer. I get better all around MPH, but about the same on the highway.
I was hoping that MPH on highway would be better. Since most of my driving is city/highway I really can't complain.
The noise level is about the same, until you put your foot in it. Then you hear the difference. My wife does not appreciate the unit at that point. Appearance, the thing really looks cool up there, and opens up the engine compartment for better access to the motor.
The real test will come when I tow my boat! Would I buy it again? YES
Installation with instructions was very easy. Step by step procedures, as well as step by step photos included in the package. Marth Stewart could even install this kit." —George K from Lynnwood, WA bought a K&N 77 Series Metal Intake Kit for a 2003 Chevy Trailblazer, 4.2L 6-cyl. engine.
"Like always K&N makes a very good product and Autoanything has the best price match policy out there. Installed in about a half hour works great, looks great, and sounds great." —Gabe D from Aztec, NM bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Trailblazer.
