🚗 K&N Cold Air Intake Kit: Boost Horsepower, 50-State Legal: Compatible with 2002-2005 CHEVROLET/OLDSMOBILE/GMC (TrailBlazer, Bravada, Envoy), Part 57-3036 Review

Power is felt at all rpm ranges, but as you rev up the power only builds until the engine shifts into a higher gear, and then you do it over and over again. I built my own intake system at…

I purchased this product from Revain about a year ago. I hooked it up in about an hour with no issues. I understand that many of you don't read instructions the way I do, but in this case I strongly recommend doing so. If you don't follow these, you'll be missing out on important steps that are essential to installing an air intake. There's no gas mileage benefit, so keep your Benjamins if you're looking for them.
