I fit this filter in an EK4 Honda Civic factory air box.. Very Happy easy install and good throttle response
Sean Day, Lake Stevens, Washington
The filter was very easy to install and should be the last air filter I ever buy for this vehicle. I'm very pleased with its performance.

Great item and perfect fit. Installed at the same time as new plugs and wires, as well as a switch to synthetic oil. Change in my CRV is noticeable. Even if the K&N is only part of the improvements, for the cost and not having to replace it, just clean it occasionally, it is a great investment.
