Dealing direct with K&N is always a pleasure. Instant invoice was recieved and super fast shipping of the product. I've used their air filters on all my cars over the last fifteen years. You can expect better perfomance, a little better gas mileage and a deeper exhaust sound. Very pleased with this product. I would certainly buy again and recommend to a friend.

Great product! Increase in horsepower and fuel efficiency. I now have it in both of my vehicles.

Couldn't believe how restrictive the original equipment air filter was . After installing the K&N replacement , the motor seems smoother and more responsive . The great gas mileage of my Subaru appears to have improved also .

Hallo. Möchte mich bedanken für den Super Ersatzluftfilter 33-5064 für meinen neuen Subaru xv ( crosstrek ) Modell 2018. Er sitzt perfekt im Luftfilterkasten und man merkt auch deutlich den Leistungsschub. Ich bin schon seit Jahren ein großer Fan von K+N Filtern und habe ihn auch in meinem Mazda B 2500 Pickup verbaut. Auch mein alter Toyota RAV4 fuhr mit diesem Filter. Kann nur sagen top, große Klasse eure Filter. Ein muss für jedes gute Auto. Vielen Dank.

While throttle response seems better, my MPG has dropped from 27 to 21 for no other reason than I swapped air filters. Not what I expected.

This has worked flawlessly and provided an appropriate amount of responsiveness from the engine. Acceleration at start, and shifting between gears is made easier with that little bit of additional power and has made driving my Subaru Impreza more engaging. My only negative feedback for K&N is the lack of Cold Air Intake products for my model car (the 2017 and 2018 Impreza models are very different from previous years and there are few aftermarket options available from any company). I'd be willing to spend more and get more, but this Air Filter has given me exactly the right bang for the amount of bucks I spent.
