This Crossover R-Design is both a dream to drive for my wife and two children AND is a 350 hp monster when I step on the throttle. The K&N air filter is a long term investment which protects my engine as well as just plain delivering a noticeable improvement in acceleration and an enhanced exhaust note upon hitting the gas. Bravo... I'd buy it again.

Purchased two filters for our F-150 and Volvo S80 T6. Definitely can feel the difference. Hopefully they are easy to clean and last.

Installation in 2016 S60 Polestar very easy. So far seeing a slight increase in MPG during highway driving, but really too soon to validate.
