Faster spool +1. 5mpg, stronger sound
"Install kit was perfect, super easy and video instructions were step by step and flawless. Very high quality, even the hardware. They include everything including the thread locker. One suggestion, leave off the included spacer - just use the factory washer for the side air box bolt for more filter clearance, will make maintenance access easier. Much deeper sound, especially with exhaust brake deceleration. Much better throttle response due to faster turbo spool. Highly recommend!"
