Cold Air Intake for Dodge Ram 2500 / 3500 (1994–1998) 5.9L 12V Cummins Diesel
Unlock the true potential of the legendary 12-valve 5.9L Cummins Diesel with this precision-engineered cold air intake system. Revered for its mechanical simplicity and bulletproof reliability, the 12V Cummins is a favorite among truck enthusiasts, yet it is often stifled by a restrictive factory air box designed for silence rather than power. This upgrade replaces the stock assembly with a high-velocity induction path, allowing your engine to breathe freely and delivering a boost in horsepower and torque by up to 10%.
By capturing cooler, denser air from outside the engine compartment, this system optimizes the combustion process for more efficient power delivery.1 Whether you are hauling heavy equipment, towing a trailer, or simply cruising the open road, you will notice a significant improvement in throttle response and smoother turbo spool-up. The increased airflow efficiency doesn't just add power; it also supports better fuel economy, ensuring your classic Ram operates at peak efficiency.
The system is constructed from premium T304 lightweight aluminum piping, providing a durable and heat-resistant channel for incoming air. The smooth internal surfaces significantly reduce airflow turbulence compared to the factory setup, promoting consistent air delivery to the engine.2 Under load, the intake rewards the driver with a deep, throaty induction note and that signature turbo whistle that defines the Cummins driving experience.
Maintenance is simplified with the high-flow synthetic air filter. Engineered for superior filtration and maximum air volume, this filter protects your engine from dust and debris while allowing for a much higher air mass flow than standard paper filters. Because the filter is fully washable and reusable, it requires cleaning only every 50,000 miles under normal conditions, offering a cost-effective and sustainable alternative to disposable components.
This intake system is designed as a direct-fit performance solution that installs in less than 60 minutes using basic hand tools. It utilizes factory mounting points for a secure, professional fit and is engineered to work within factory parameters, ensuring it functions seamlessly with your vehicle's existing setup without voiding warranties.

If you are looking to improve the breathing, responsiveness, and overall power of your 12V Cummins, this cold air intake is a well-balanced performance upgrade. For optimal results after installation, the battery terminal should be disconnected for 1 minute to allow the engine computer to recalibrate to the increased airflow.
