2003-2018 Cummins Stage 2 Performance Head (DJPCH100031)

Fits

Designed for the performance enthusiast; Featuring a D&J Stage 2 Billet Intake Manifold, thread-in soft plugs in the head, titanium valve spring retainers, and HD extra-large valve seats. This Stage 2 Cummins Performance Head gets the intake flow up to 250 CFM and is the biggest head D&J has available for a 5.9 bore engine (stock is 165 CFM).

D&J has seen the stock seats fall out, these HD extra-large valve seats fix this problem. Also, occasionally the soft plugs under the valve cover come out, filling the crankcase with coolant. The thread in soft plug solves this issue, and with the Billet replacement style intake manifold. You can keep the factory rail, lines, map sensor, fuel filter housing, air horn and throttle position sensor.

Some of the intakes with side entrances force air into the cylinders across from the inlet pipe, D&J has witnessed the cylinders across from the inlet run 300-400 degrees hotter. In some cases, even melting pistons. Since this intake utilizes the factory air intake mounting, this allows the air to disperse more equally throughout the entire intake manifold. This also saves the customer time and money by utilizing their current intake horn.
