The Pusher 3" Cross-Air works with the factory intake manifold or any factory replacement manifold and is the most cost-effective way to protect your front and rear cylinders on trucks under the 500HP mark. The Cross-Air adapts to existing ports at the front and rear of the intake plenum that is normally sealed off with 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 can be better supplied with air. This helps balance the engine temperatures and load at each cylinder greatly. 

To ensure optimal penetration without impacting airflow, this entire package has been fully TIG welded and utilizes mandrel-bent tubing. With this kit, you will notice a significant drop in EGT's due to better-equalized airflow to cylinders 1, 5, and 6, as well as an increase in fuel mileage, throttle response, and turbo spool!
