Enhance Your 5.9L 12V Cummins with Upgraded Intercooler Components

The factory intercooler system in early Cummins trucks can be restrictive and prone to leaks under high-performance applications. Upgrading to a high-flow intercooler and reinforced piping reduces turbo lag, increases horsepower, and extends the life of your engine by preventing excessive heat buildup. Our selection of intercoolers, pipes, and boots offers:

• Performance Intercoolers – Larger cores for improved cooling efficiency.
• Heavy-Duty Pipes – High-flow mandrel-bent tubing for reduced restriction.
• Reinforced Silicone Boots – Durable, high-pressure boots to prevent boost leaks.
• Complete Intercooler Kits – All-in-one solutions for enhanced performance and reliability.

Whether you're upgrading for towing, off-road performance, or daily driving, a quality intercooler system is essential for getting the most out of your 5.9L Cummins engine.
