    • Perfect fit and high quality.
Size: (Pack of 1)
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. ... show more

    • Perfect fit, top quality.

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. ... show more

    • Perfect fit 2023 Subaru WRX

We will see how long it will last as I’m not sure how durable it truly is. Price was decent for what it is and I’ve always liked K&N filters. Visually it looks a lot nicer than other paper style filters.

    • Very good quality comparable to OEM at a much more reasonable price point.
Size: (Pack of 1)
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

    • Excellent quality replaceable engine air filter.
Size: (Pack of 1)
K&N makes very good replaceable filters, like this one. Their reusable filters are more targeted toward performance machines, and are not as good at removing contaminants are these replaceable filters are.
