You will have faster spool up, lower egt's, Noticeable Horsepower gain, some Mpg gain, and a turbo whistle that will make people look when your going through town!
Has a bolt in heat shield that is vary well sealed to keep underhood temps away from the air 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.
Comes with S&B Oiled Filter or AEM DRY Flow Filter
These are Custom built to order, so it take 2-3 weeks normally to ship out, depending on how many orders we are working on building.
Has RPI Logo on top of heat shield lid, we can do Custom lids that say: LB7, 6.6, or other options.
