These design features amount to an average 49.4% increase in flow over the factory manifold as this vast improvement over the stock manifold you can expect quicker turbo spool, lower EGT's and less overall strain on your motor (You will need to delete all of your factory emissions - BDD also stocks EGR delete kits for each appropriate year of 6.7L engines - kit requires exhaust work & tuning!)
*** Installation Instructions NOT included...in the pictures you will notice one side of the manifold seems to have a dent in it - this IS NOT damaged in shipping - this is designed to allow the fuel supply line to be utilized in its original OEM position! It's NOT a defective manifold & is deliberate! Please see the 2nd picture with the fuel line...…if this is your first time installing or deleting a Cummins engine we recommend you research what all expenses and items that will need to be incurred to do the job right! We don't want any upset customers from a check engine light illuminating!
