My K&N filter thoughts...

I am not too sure. I am losing mileage with the same driving habits as compaired to my stock paper filter.

Here is the weird thing.

When I drive harder, my mileage goes up.

I installed the filter when I was at half-a-tank...I usually wait to do a mod on a fresh tank, but I wanted to throw it in there. I am using the AVG mileage reading from the first half of the tank on the stock filter, and from now on with the K&N. Don't know if that matters or not.

I love the small [if noticable] difference in power, but watching my mileage drop slowly while driving on CRUISE is causing me to become confused. Who said 45mpg? I called BS on that then and I still will.

Anyway, I'll be needing gas come the beginning of the week and we'll see what happens. I plan on running the 93 tune again at the next fill-up, and then switching back to 87.

Maybe I need to smoke the computer and reset the battery after installing the filter -- I always did on my other vehicles when I did the K&N FIPK. Hmm...

Anyway, when I drive harder, I gain mileage. Odd.

I mostly drive streets and before the k&n i was getting about 260 miles on 16 gallons, 300 miles when I traveled more on the freeway. I Installed K&N filter and removed the silencer box a few weeks ago. I'm now getting 270 on the street. I just took a trip yesterday to Tijuana Mexico, cruise control between 85-90mph both ways, I have 301 miles on the trip odometer and a 1/4 tank left. "68 miles to E". Only other factor to affect this increase is I switched my 19's for my stock 17's for the trip. If your wondering, yes I got a speeding ticket, 84 in a 65 NOT EVEN 5 Miles across the US border!
