Every car we buy gets a K&N air filter. They are low maintenance and provide added fuel efficiency and power.

Easy to install on my 2017 Impreza. Really did improve performance. Well worth the money. Will be purchasing for my other car. Thank you for a great product.

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.

I think every vehicle I have owned has had some type of either CAI or drop in filter added to it. In this instance I added a drop in filter to my 2018 Impreza Sport. As all the reviews point out the CVT transmission can be on the sluggish side. I feel that the K&N drop in filter added better throttle response and woke it up so to speak. The low cost and durability of this product make it an easy add on for any vehicle. Thank you K&N for your continued ability to produce quality automotive products.

Arrived by ETA date. Easy to install. 2017 Subaru Impreza Sport 4 door sedan. Had a oil chage prior to install but once it was ready to go noticed a huge difference. Car accelerates quicker but really haven't noticed a change in MPG. Great substitute for a cold air intake system. Highly recommend this air filter especially if your worried about voiding the manufacturer warranty.

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.
