Freightliner Coronado with 12.7L Detroit Series 60 Engine
I love my AirDog. I installed the AirDog myself. It works great on my 12.7L series 60. The people are great too. I have tracked a .2-.5 MPG increase, along with smoother idle throughout RPM range and improved throttle response. My engine used to crank for several seconds to fire up, but now it starts instantly. I also used to lose prime on injectors, but now it’s not an issue with the AirDog. Thanks for a great product.
