Always trusted K&N
I have a 2019 Alfa Romeo Stelvio and this was easy to install. Just had to disconnect the Maf sensor and the goes connecting to the air box. Took me around 5 minutes to install. I’ve always used K&N filters on all my vehicles. In the, future I’ll be switching to a K&N CAI. These filters are good quality and a good value for your money. Best part is you can wash them and reuse them. It was pre oiled and fit perfect in the air box. Highly recommended.

Top quality filter built to last
Well made and good air flow. Have removed and cleaned a couple of times now and it’s still going strong.

Immediately noticeable improvements
Perfect fit for my Giulia Sport Ti. Immediately noticeable improvement. You can definitely tell you're getting a little bit more power. But the best part is the improvement in sound, you get a slightly louder lower pitch grumble from the engine, but most impressive is how much more you can hear the turbo. Definitely a must have for any Giulia owner, and much cheaper and easier than installing an entire new intake.

Good replacement option but getting additional power is an overstatement
Compared the the oem filters of the car, this is a good reusable replacement that can be cleaned and reused unlike the oem paper filter. Fit was perfect on a 2020 stelvio ti but a little lucrative to replace due to the way the intake is setup on the car. Works as expected but there is no power increase. On modern cars the intake is computer controlled and a filter won't change that unless a tune is perform, and even so, it won't be because of the filter

Worth It To Me
I did notice an instant increase in throttle response. Also notice better mpg in general…city and highway. I’ve used K&N in other vehicles I’ve owned and you kinda can’t go wrong with them. Perfect figment and saves money in the long run because these are reusable with a cleaning every so often. Might grab one for my wife’s car.
