Bada** filter. I use it on my dump truck and work all day in the calichie. .. thing still looks new. Seems like it has better throttle response, too.

Very good replacement filter. Used it on my 2011 international prostar running the Cummins isx, and it picked up a little power and torque. But really bought it for fuel mileage and it has already paid for itself in two weeks. I average .8 mpg better than before.
