I was hoping this to fit, have all my family's cars with K&N. The stock filter has tabs on the sides and hold a leveler you turn to push the filter up in side against the intake on the the box. This item sat flat on the bottom of box with a 1/4 inch gap.

I ordered this filter online, however it did not fit my particular year vehicle. When I called, the customer service representative advised that per my VIN number, my car was made prior to the current filter size and that no replacement was available. I was offered a return shipping label in order to return the filter at no cost to me. The representative was very polite and helpful during the entire process. It was also helpful to know about the different filter sizes as they pertain to dates of manufacture. While I did not get the replacement filter I wanted, the entire experience was positive and I will order K&N filters for my vehicles in the future.
