 This is a great, cheaper alternative than buying a regular air filter at $30/filter. I only wish that K&N made a cone filter for this model vehicle because I had a great experience on a 1993 Mercury Cougar that I installed a Cone Filter for. I find the cone filters have higher air flow and better response, but the washable filters are still a great recommended buy.

 The best! 2011 CRV 33-hwy 22-city. Now K&N makes a cold air intake for 2011 CRV.

 Fantastic product! My Fuel Rating has increased by 3 MPG while the vehicle shows much more power. I have cleaned the filter one time and that was a breeze!
Will be purchasing two more filters for my other two vehicles!

 Love this filter in the 2010 Honda CRV. It really woke up the engine and performance. Went from 26 city 28 highway mpg to 28 city and 30/31 highway so it is paying for itself.
