13-18 Cummins Pusher 3.5 Mega Intake System

Features
Intake Manifold- the Pusher Intake Manifold is built around a 3.5" inlet that smoothly transitions to two 3" mandrel bent tubes. This design also enabled the use of a short bolt in place of the long driver-side flange bolt that passes right through the center of the stock manifold air plenum. Thus freeing up airflow even more yet maintaining the stock six bolt pattern for a proper seal. The twin tube design nearly doubles the outlet size of the stock manifold while minimizing the impact of the initial section of the number one injector line. These design features amount to a 49.4% increase in flow over the factory manifold. With this vast improvement over the stock manifold you can expect quicker turbo spool, lower EGT's, and less over all strain on your motor. This manifold also includes instructions, a polished stainless dipstick mount, port plugs, a OEM gasket and hardware to make installing this intake extremely easy. You will need to delete all of your factory emissions equipment as the manifold does not have provisions to use any of it. This manifold is for off road use only. 

Intercooler Tubes - the Pusher intercooler tubes are built around 3.5" mandrel bent tubing. These tubes help optimize your factory intake plumbing by replacing the stock 2.75" driver-side and passenger-side tube. This kit also includes heavy duty 4-ply silicone couplers and stainless T-bolt clamps to make installing these tubes extremely easy. When using this kit, you do not have to try and cut the factory steel bands off the factory tubes in order to reuse the factory boots. Just loosen the factory clamps and install the supplied parts.
