Ease and performance

Reviewed By Ted T (Scottsdale, AZ) Reviewed for a 2006 GMC C/K 2500 —2/4/2012 8:45 AM

It was very easy to install and I am very satisfied with the difference that I have noticed in performance and increased miles per gallon. I drive a 2006 GMC, 2500 HD, crew cab, with Duramax 6.6liter and am getting about 10% better MPH.
