Just wondering how many of you have changed to a K an N filter and what effect it had on your engine. I'm looking for an easy way to lean up port injection. What's your opinion on the filter?

I have done a back to back test at the track between a new paper filter and a new K&N filter without picking up anything. By running without any filter at all, I picked up from .05 to .08 in the 1/4 mile over both the paper and K&N filters.

The only experience I've had with K&N was BAD. I built engines for a 3 car team that ran dirt tracks for five years and when they switched from paper filters to K&N they trashed 2 good engines from all the dirt the K&N let into the engine. When they switched to Amsoil filers they got better performance and cleaner air than the paper filters. No more brown stuff in the top of the carb.

I put one on my Ford Probe GT. At the track it picked up about 1 1/2 mph through the traps over it previous best and about 1+ mpg. I would not hesitate to use one in any of my cars.

No offense to you Big Gear Head, but I've run
the same K&N on my dirt car for three years without a problem. Of course I clean it every week and re-oil it. You wouldn't believe all the dirt that comes out of this thing! I see a lot of guys at the track spending money on paper filters every week and personally I think it's a waste of money. I don't know what affect it has performance wise on my engine, but I can tell you it saves me money!!
