Wehrli 4-inch intake kit for 2007.5–2009 Cummins 6.7L replaces the factory intake plumbing to increase airflow to the turbo while retaining use with the stock turbocharger. The kit includes a dry air filter and pre-filter cover and is finished in Bengal Grey for a dressed engine bay. Engineered to work with the factory turbo, it improves intake volume and flow for better throttle response and cooler intake temperatures without modifying the turbo itself.
