The KN engine filter is exactly the one I need for my 2019 Subaru Outback. It arrived in a timely manner so I could install it prior to leaving on a vacation. I love the fact that it can be cleaned and used multiple times for many miles to come.
I've used K%26N filters for years in my own cars. My daughter is trying to learn how to maintain her car herself after she paid $50 to have her air filter replaced at one of those quick oil change businesses. I've had my filters in my truck for 5 years, and they paid for themselves in the first two oil changes. they are easy to clean, I feel like they work better, and they don't end up in a landfill somewhere. I highly recommend these filters to anyone who doesn't like wasting money. if you change your air filters every the months like recommended, you could be sinking over $100 a year into something you're just going to throw away. even more if you pay someone to change it for you.
This air filter fits perfectly on a 2013 Crosstrek. I measured the size and fit, which is the exact size of the AEM filter, but it costs less! Just to let you know, this filter is thicker than the oiled K%26N, so please be sure to disassemble the air filter tube to fit this filter.
This is a great filter. I an clean it myself and put it right back in. Just hose it off. No more buying these everytime I get ny oil changed.
This filter will pay for itself quickly. When dirty, just remove, wash and reinstall. K%26N has always been synonymous with quality.
It's K%26N. is there really anything else to say?
You need this filter!!! This is an important investment in your car's performance and reliability. I love that it's reusable and this one air filter can last up to 30 years!
Great price, box was perfect and undamaged.
Ease of install…price very good for washable filter….build quality was solid
It's a great product
