I use K&N on all vehicles that I have owned. It has always given extra MPGs and extra HPs. Always easy to install, easy to clean and maintain. if you keep your vehicle as long as I do (my last two vehicles, a 2001 Toyota Sienna lasted 18 years, and 2000 honda civic LX lasted 17 years), this filter pays for itself and more! definitely worth the price. I bought one now for my new Honda Civic EX hatchback which I will also drive until it breaks which could be 2 decades from now - imagine how much I will save on regular air filter purchases and extra mpgs. very well worth the price!

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.
