Industrial Injection 98.5-02 Dodge 24V Engine Fire Ring / Ported Valve Bowls / CNC Exhaust Port

What you get with this Industrial Injection cylinder head package are fully prepared heads ready to bolt onto your 1998-2002 Dodge 24-valve Cummins engine. This isn't just a stock head; it's been significantly upgraded to handle more power and improve airflow. The package includes the cylinder head itself, featuring a robust fire ring for enhanced sealing under high cylinder pressures, precisely ported valve bowls to smooth the intake and exhaust flow, and CNC-machined exhaust ports for optimal gas evacuation. These modifications work together to help your engine breathe better, which can lead to improved performance and durability, especially if you're pushing your truck beyond its original specifications.

The fire ring is a critical component for high-performance diesel engines. It's a metal ring that sits in a groove on the cylinder head deck, creating a very strong seal against the combustion chamber. This is especially important when you're running higher boost pressures or making more power than stock, as it helps prevent combustion gases from escaping the cylinder. The ported valve bowls and CNC exhaust ports are designed to reduce turbulence and restriction as the air-fuel mixture enters and the exhaust gases exit the cylinder. This improved airflow means the engine can fill and empty its cylinders more efficiently, allowing for more power to be made and potentially better fuel economy under load. Industrial Injection is known for its work on Cummins engines, and this head reflects their experience in building components that can withstand the demands of these trucks.

When installing these heads, it's important to follow the manufacturer's recommended procedures, especially regarding torque sequences and any specific break-in requirements. Because these are performance-oriented heads, they are often paired with other upgraded engine components to take full advantage of the improved airflow and sealing. Ensure you have all the necessary gaskets and hardware for a complete installation. Please note that this product is not CARB approved and cannot be shipped to California.
