Cold Air Intake Kit

The HSP Diesel Cold Air Intake system is engineered as a direct performance upgrade for 2020-2025 Chevrolet and GMC L5P Duramax trucks. Constructed with smooth 4.5-inch mandrel-bent aluminum tubing, this intake is designed to provide a consistent flow of cool, dense air to your Duramax engine. It boasts a significant improvement, offering 88% higher airflow compared to the factory stock system. This means no engine tuning is required after installation, simplifying the upgrade process. Precision-molded Santoprene TPV inserts are incorporated to create a tight seal against both the fender and hood, ensuring that all incoming air is directed into the intake system without any loss. Included in the kit is HSP's proprietary MEGA 4.5-inch oiled filter, which provides maximum surface area for superior filtration and airflow. The product also comes with a "NO BS" Limited Lifetime Warranty from HSP Diesel, underscoring the company's commitment to quality and customer support. Note: Some trucks may require disabling the factory Air-Filter Life System (AFLS) to prevent "Change Air Filter" messages due to the increased airflow. The procedure involves navigating through the Driver Information Center (DIC) options to disable this reminder, which has no adverse effect on vehicle operation.
