Best Air Filter EVER
I have used these in my cars for years. They improve turbo lag significantly, increase air flow, and just work. What I like best about these, beside the protection they offer the air intake system, is that they truly are a life long product. My last car had one in it for 13 years. With a cleaning every 25K miles as outlines by KN the air filter just continued to work and work.
I recently purchased one for my new Honda CR-V and had it installed at the dealership at 500 miles when I was getting an oil change to flush out the build lube. The mechanic who did the work left me a note that said "great filter, I love these"

Worth it! Love these filters.
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
