I drive a 1999 Ford Contour SE with the 2.0 liter I4 Ztec motor. After installing the filter, I experienced significantly greater accelleration, and though I didn't expect it, the tone of the engine's revs took on a more profound, stronger note.

Sold for life on these filters

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.

I have a 2.5 v6 Mercury Cougar, and she's thirsty running at about 19mpg... My trip computer is showing 25 mpg on stop start, and 31mg on a run! I'd just had the car serviced, complaining to the dealer about the MPG, and a £900.00 service later there was some improvement. But when I went to change the 2 month old paper filter it was CAKED in crud... I can't believe such a small and easy fix could give me these excellent results!!!
