Good product, not much to say. The product arrived quickly, looks to be of high quality construction, fit perfectly and took me only a couple of minutes to install. I love it when a product is no frills and delivers as advertised. I’ve used various filters from K&N before and have always had very good success with them so I will be buying more of these for sure when the time comes.

My college- agreed daughter drives her Subaru through all sorts of off-road environments as an Environmental Biologist. I trust these filters more than any other in the market to keep her engine in top condition. Spend the few extra bucks and get these ones that will last long after the cheapies fail.

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.

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.
