K&N Cold Air Intake Review

K&N Cold Air IntakeK&N's kit sounds great and performs well, and we documented a solid gain in performance AND fuel economy after installing the kit. Unfortunately, installation is the problem with the K&N 63 series. The install process is tedious (compared to other air intake installs) and it's more complicated than necessary.

Complication increases the chance for errors, as witnessed by the filter falling off the test truck. We also can't help but we feel that the K&N kit should be less expensive than its competitors considering so much of the assembly is done by the end user.

We recommend the aFe air intake kit over the K&N 63 series air intake. Performance is similar, but aFe's kit is much easier to install and there is less that can go wrong.

"I personally installed this kit 13 months ago. It took a bit of my time but was manageable. The parts could have been of better quality (plastic threading was messed up and the heat shroud is bulky and somewhat useless). My main problem with this unit was keeping the filter bolted on! It took a little work but I used a wider band for the clamps and since then have had no trouble. Overall, it sounds very nice, especially on hotter days. I feel the increase in power and performance gain although not dyno-tested. And there is a small increase in MPG as well (about 1.5 MPG better after install). There is a kit to clean/oil the filter and it is very easy, affordable, and doesn't need to be done often. So far, no issues with it and I like it as a reasonable upgrade for my truck."
