1998.5-2007 5.9L Cummins Billet Intake Spacer Kit. This high-flowing CNC machined billet aluminum plate allows maximum airflow from the intake horn into the cylinder head – increasing turbo spool up and performance. Unlike many other options on the market that utilize frustrating, single-use lead-type gaskets for installation, we have incorporated O-ring seals on each side of the Intake Spacer Kit for clean, simple installation, and easy swap back to the more restrictive grid heater assembly if necessary in your region/colder climates. This Billet Intake Spacer Kit matches perfectly with our 3.5” High Flow Intake Horn and Intercooler pipe for the highest possible flowing intact tract but is also compatible with OEM and other aftermarket intake horns.
