Big improvement on accelerating. Don't know on mileage yet.only one of fuel so far. Very easy to install. Most of my driving is off road.

Wonderful system, it is a tight fit. I noticed a HP difference right away. My only issue are the screws. Two have loosened and fallen off. Others are getting stripped out. I'm waiting for a call back from K&N to see how I can get a replacement set of screws.

I have an 05 F 350 4x4 DRW. I have noticed an increase in throttle response. The truck pulls much better than before. And I get an increase of 2 mpg at minimum or better. This is driving 80 mph and not letting off up the hills. I installed this right before a 2000 mile trip, and I wanted to get a true reading on the mileage increase and power. It's worth the $400.00
