Range Active Fuel Management Disable Device


I had the chance to install it in Saturday and I immediately noticed the difference, I always knew when it would go from 8 cylinders to 4 by the tone of the exhaust and I always felt the hesitation when I stepped on the pedal at cruising speeds. Once I installed the Range AFM it stopped those problems. Quick and easy fix. Thank you View more reviews...
