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

Gives my truck more power. Have not had it on long enough to see if gas mileage improves.

I bought the cold air box for my 2006 Ford F350, one year ago. The filter was just taken out for the yearly cleaning. Very nice system. I have seen an increase in mileage on the highway when towing my 5th wheel. Thank you for a great product.
