Product Description
The CPP DIESEL PERFORMANCE COLD AIR INTAKE SYSTEM is engineered specifically for 1991-1993 Dodge Ram trucks equipped with the legendary 5.9L 12V Cummins engine. Designed to improve airflow, turbocharger efficiency, throttle response, and overall engine performance, this intake system replaces the restrictive factory intake setup with a high-flow washable filter and large mandrel-bent tubing.
This system features durable 4-inch mandrel-bent intake tubing for smooth unrestricted airflow directly to the turbocharger. The included reusable high-flow air filter provides excellent filtration while supporting increased airflow for towing, street performance, and daily driving applications.
The CPP Diesel intake system is compatible with stock chargers, modified stock turbos, S300 turbo setups, stock exhaust manifolds, and aftermarket manifolds in factory orientation. The kit also includes a heavy-duty silicone coupler and stainless steel clamps for long-term reliability under boost.

WHY UPGRADE THE FACTORY INTAKE?
Factory first-generation Cummins intake systems were designed primarily for noise reduction and packaging constraints. Upgrading to a larger high-flow intake system reduces restriction, improves turbocharger airflow, helps lower exhaust gas temperatures, and supports improved towing and performance capability.
The mechanically controlled VE-pump 12V Cummins engine responds especially well to airflow upgrades because improved intake efficiency can help maximize turbo response and overall drivability.
