I love K & N air filters and always install them in my cars. This eliminated my cars Turbo lag in my 2019 Honda Civic Ex which has a 1.5L Turbo. Acceleration has improved and makes the car louder (I also have dual exhaust) I love how you don't have to change or clean it for 50,000 miles!! I know it's expensive but will last forever! Only issue was it was very difficult to install and a pain but this is more Hondas fault as I could not fully remove the plastic case where this filter goes under the hood even with tools.

More power and better mileage

Put this in my 2017 CRV and have noticed much more pickup and better mileage overall. Usually I average 22mpg with mixed driving and this has me hovering around 25mpg and I get to have extra power on top of that. Install was straightforward and a breeze. Whole project is done in ten mins and your car is instantly more fun and getting improved MPGS

Improves the air quality of you vehicle

Perfect fit. You can tell the difference in the quality air recirculation. Without a doubt an improvement over inexpensive filters. I highly recommend replacing any auto air conditioning and heating with this filter.
