he Gold Standard in Air Filters
This product works just as intended. K&N has been a leader in lifetime air filters for a long time, and their reputation for quality is well-deserved.

Been a K&N customer for over 20 years.
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"
