You will have faster spool up, lower egt's, Noticeable Horsepower gains, some Mpg gain, and a turbo whistle that will make people look when your going through town!
This is a direct bolt-on intake system.
Has a bolt in heat shield that is vary well sealed to keep underhood temps away from the large Filter, it provides a fresh cold air supply straight to the filter for lower egt's and better performance. It is normal to see 150-250 deg drop in egt's with this system.
We use only the best filters on all our intake systems
