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 EGTs 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. 

APPS Compatibility:

This kit is not compatible with the APPS mounted in the stock location on 2003-2005 trucks. You must relocate or purchase the Pusher APPS relocation bracket to use the Cross-Air on trucks equipped with a APPS.  

Intercooler Compatibility:

This product is designed to be compatible with the factory intercooler and will also work with aftermarket intercoolers that maintain the same inlet and outlet configurations as the factory setup. If your aftermarket intercooler features different inlet or outlet locations or sizes, please contact us to verify compatibility.
