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!
