  • Perfect fit. Takes less than 5 minutes to install
Great replacement filter that takes only minutes to install. Save major $$$ by doing it yourself. If you aren’t sure how to install it, there are videos showing how easy it is on YT.

  • Very good quality comparable to OEM at a much more reasonable price point.
Last December we bought our first new car in 21 years and the first thing I did is stock up on cabin and engine air filters. I've got nothing against dealership OEM parts and pieces but what I do have an issue with is the prices. Luckily, we all have a bit of control over access to OEM quality parts and pieces at significantly more reasonable prices via Amazon. This filter and it's matching cabin filter are excellent in value and take less than 5 minutes to replace. Compare that to paying the hourly rate at your dealer plus the dealership retail price and you'll do what I did and stock up on these two filters. Definitely recommended. ... show more

  • Worthwhile purchase
Works just as intended. Fan of K&N products. If you don't want to get the million mile reusable K&N for your vehicle, this is a good alternative.
