The Cross - Air System is the most cost - effective way to safeguard your front and rear cylinders, especially for trucks under 500HP. It attaches to existing ports at the front and rear of the intake plenum, which are normally sealed off by the factory.

The whole package is TIG - welded and uses mandrel - bent tubing to ensure optimal airflow. You'll notice a big drop in EGTs, along with improvements in fuel mileage, throttle response, and turbo spool. Features include cost - effective cylinder protection, adaptability to intake plenum ports, better air supply to key cylinders, TIG - welded and mandrel - bent tubing, lower EGTs, increased fuel mileage, better throttle response, and improved turbo spool. The kit includes machined cylinder head adapters, heavy - duty 4 - ply silicone couplers, stainless T - bolt clamps, and all necessary hardware. Optional powder - coating colors are available for an extra charge. If you have a 2003 - 2004.5 5.9L Cummins 3rd Gen Dodge with an APPS sensor, you may need a relocation bracket.
