The Pusher 3.5" MEGA Intake System with replaces your stock post-intercooler piping and intake manifold with 3.5" mandrel bent tubing, significantly increasing the flow volume and efficiency of your charge system. The Pusher Intake Manifold is built around a 3.5" inlet that smoothly transitions to two 3" mandrel bent tubes. 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. Our design also allows for 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. This frees up airflow even more while maintaining the stock six bolt pattern for a proper seal.  

With this vast improvement over the stock manifold you can expect quicker turbo spool, lower EGTs, and less over all strain on your motor. This manifold also includes instructions, a polished stainless dipstick mount, port plugs, OEM gasket and hardware to make installing this intake extremely easy. This manifold is for off road use only.  

Our 3.5" intercooler tube is built using mandrel bent .060" thick tubing, and is a drastic improvement over factory 2.4" ID plastic plumbing. Our intake system also includes heavy duty 5-ply silicone couplers and stainless T-bolt clamps to make installing this tube extremely easy. When using this kit, you do not have to try and cut the factory steel band off your tube in order to save the factory boots. Just loosen the factory clamps and install the supplied parts.  

Intercooler Compatibility: This product is designed to work with the factory intercooler and is compatible with aftermarket intercoolers that replicate the factory inlet and outlet locations. If your aftermarket intercooler differs in design, please contact us for compatibility information.

By replacing your restrictive factory system with a Pusher Intake System, you can expect results of:

• 50-200 degree Fahrenheit drop in EGTs
• 0.5-1 mpg increase
• Significant gain in throttle response
• Faster turbo spool
• Increased durability

In addition to the intake manifold and intercooler tube, our system includes factory Cummins gaskets and hardware, heavy-duty 5-ply silicone couplers, stainless T-bolt clamps, port plugs, a stainless dipstick mount, and detailed, full-color instructions with photos—everything needed for a smooth and seamless installation.
