I just got this product yesterday and since putting it in my 1999 ford escort I feel more power out of it the acceleration is better. This product is amazing. The only thing is I wish I could find the cold air intake pipe for my car.

Ever since I installed the K&N air filter in my '95 Ford Escort LX, I've noticed a great improvement in my car's performance compared to the factory's paper filter.

In January of 2008 I purchased a K&N air filter for my 2000 Mercury Grand Marquis.  I admit I was skeptical that an filter would make any difference in performance or gas mileage.  Within three months, taking into account the difference between the original gas mileage and my increased gas mileage, the filter paid for itself.  Before I changed the filter to a K&N I would be lucky to get 14.5 mpg in town and 22.4 mpg on the highway.  With a 4.6L V8 I didn't expect much of an improvement.  To my surprise my I now get 17.4 mpg in the city and 27.5 mpg on the highway (confirmed on a recent trip from Kansas City to South Carolina).  Plus, I'm getting excellent performance from the car.  Needless to say I'm VERY pleased!!!  In May of 2008 I also replaced the paper filter in my wife’s 1995 Ford Escort wagon that has more than 150,000 mi..  Before I replaced the filter with a K&N filter I would get 19.5 mpg in town and maybe 24.5 mpg on the highway.  Now it gets you 21 mpg in town and 26 mpg on the highway, and it runs like it did when it was brand-new.  Why should anyone NOT get a K&N air filter?  Terrific Product!!!
