K&N 38-2025S Air Filter Product Reviews

Monday, April 17, 2017 - Part 38-2025S
In the 2 days I was running with it before an elk decided it wanted to ruin my week, I was already noticing performance increases and higher mpg's.

I picked up the K&N Heavy Duty Replacement Air Filter for my Volvo Tractor Trailer after I arrived at the 76th Annual Sturgis Motorcycle Rally. I had heard about these now for 2, maybe 3 years without consideration of any type of performance gains. These filters are built tough. Installed with ease in about 10 minutes. On our way home to Indiana, we realized .5 mpg better hauling 74,500 lbs and 1.0 mph light load better. I highly recommend this filter. 300,000 Warranty to boot? Thanks K&N
