This air filter allows my 3.9 V-6 to breathe. I now enjoy the original torque this engine once had, plus the take off is pretty sweet. It hasn't done what I would have liked...increase gas mileage, but it runs smoother and sweeter.

Gave my truck great harmonics, and it doesn't smoke as much. 10/10. I will recommend to everyone I know.
