I love K&N filters, I have one on the engine intake too. I like them reusable (although sometimes I doubt the environmental impact of cleaners!) so I bought this one (also because mine has never been changed before) and now my engine has fewer problems with air bubbles during driving and use. alternating current. Not to mention the air smells cleaner. But that's just my personal experience. The real facts about the product are that it fits my car perfectly (Chevy Cruz 2014) and the build quality is high.
