K&N gave me less MPG!

In theory if they were still useing carburators, and you put on a higher flow filter, without rejetting, you would be running a leaner mix, and get better mileage, either that or burn your valves, and wear your rings and bearings out with the extreamly fine grit that it lets pass thru it.

I bought my K&N filter 3 years ago. It still looks brand new, all I have to do is spray the dust out with a airgun every 3 months. Not a bad deal at all. I payed $45 for mine. Compared to OEM filter, I saved more than I spent. I didn't buy for the mpg, but for the long life...the million mile, I wonder if my civic will last that long...

I would rather use oem filters they might cost a bit more in the long run, but they filter better then "performance" filters.

K & N won't help mpg. It lets in air more easily, so it might let in more air, which would then be matched with more fuel. You should have used that extra power it gave you more efficiently, LOL. Fram air filters are good. Pass on their oil filters.

there was no extra power, and MPG went down!! i dont get how that is possible! thats all

That's just how life is. On some cars certain things do stuff and other things don't. *shrug*

For MPG you're not passing that much air. What would happen is at higher RPMs you would have a restriction to air and go rich.
