Air filter K&N or Fram

Installed the K&N. No butt dyno difference, but overall acceleration feels smoother and there's a tad bit intake noise i can hear at WOT.

K&N if it's available. Million mile warranty, and never need to purchase another filter... ever. All you have to do is every few months take it out and clean it, then spray with the recharging oil and reinstall. I've had one on every single vehicle I've ever owned. The HP and MPG gains are smaller than advertised, but still noticeable.

Engine Info: -K&N air filter.

Out of an independent test the K&N filter earned 2nd in the least amount of particulates, with the stock filter material containing 498 particulates vs. 501 for the K&N.

I purchased a K&N air filter and cleaning kit for $50 shipped. This alone will last the life of the vehicle.

Not a whole lot of difference, that is until you swiss cheese the air box!

Just installed the K & N filters. Whoever, designed the air filter housings is a complete and utter moron! It is inexcusable at how difficult it is too change out the passenger side filter. What were they thinking. I had to chop with a knife the existing filter (passenger side only) to get it out of the tiny gap that is available. The 'G' clips are not hinged to fold back, so they act as great hooks to snag the filters. Then had to vacuum out the housings to make sure I did not leave any debris before installing the K & N's. One of the main benefits of the K & N's is that they are slimmer that the OEM's and will therefore be easier to access for future maintenance as they will slip in and out of the housings easier. THe reason I bought them is I have had good experiences with them in the past, I live at 10,000 feet and any extra air my engines can get makes a big difference!

K&N gauze construction always worry me. Lots of pinholes for dirt to pass through. People clean them too often, so it doesn't filter well (they are designed to perform dirty).

The K&N out of the box messed up the MAF on my old 2.5l Jetta, but 2.5l's are notorious for having a delicate MAF with an aftermarket intake.
