Old set up:
Z tube.
K&N round air filter jammed into stock air filter box.
New set up:
Z tube.
UTR CF air filter.
Deleted stock air filter box.
After changing my dirt covered K&M air filter back to my CF air filter. My monitors been reading 10.8 mpg at 75 mph. When I had the K& N installed I would get in between 14-18 mpg. (Yes, I know most speed limit is 65 but sometime I just can’t help myself) Then on local streets with the new filter it’s reading 8.5 mpg when I use to get around 12.-14 mpg.
I can feel a better throttle response and the sound is much deeper but 8.5-10.8 mpg? What went wrong? P.S. I’m driving it just like I did when I had the K&N.
