The Pusher 3.5" Mega Intake System with Cross-Air replaces all of your 3” factory post intercooler plumbing and intake manifold with 3.5” mandrel bent tubing, heavy duty 5-ply silicone couplers and stainless T-bolt clamps. This system provides the most airflow possible to the factory Cummins head, resulting in a significant drop in EGT's through better equalized airflow to all cylinders.

The Pusher Mega Intake System with Cross-Air increases fuel mileage, throttle response and turbo spool. The Cross-Air taps into an existing port at the front and rear of the cylinder head that are normally sealed off with a freeze plug style fittings from the factory. By splitting off the driver-side charge tube and creating two additional parallel paths to those ports, cylinders 1, 5, and 6 receive significantly better air supply, greatly helping balance the engine temperatures and load at each cylinder.  

This entire package is fully TIG-welded, utilizing mandrel bent tubing, a laser cut 1/2" flange, and 1/4" dipstick mount. 

This is a complete kit that includes instructions, machined cylinder head adapters, heavy duty 5-ply silicone couplers, stainless T-bolt clamps, an OEM gasket and hardware, plus 1/8 inch port plugs for a quality install. Additional options include various powder coat colors, and extra ports.
