CSF 11-16 GMC Sierra 2500HD 6.6L OEM Intercooler

This CSF intercooler is built with a durable aluminum core, measuring 26.5 inches by 12 inches by 3.25 inches. It's designed as a direct replacement for the factory intercooler on 2011 through 2016 GMC Sierra 2500HD models equipped with the 6.6L Duramax diesel engine. Keeping your engine's air charge cool is critical for performance and longevity, especially in these powerful trucks.

A cooler air charge means denser air, which allows your engine to burn fuel more efficiently. This improved combustion can lead to better throttle response and more consistent power delivery, particularly under load or when towing. The aluminum construction helps dissipate heat effectively, and the direct-fit design means it bolts into the factory location without needing modifications, making installation straightforward for a mechanic.

Please note that this intercooler is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and any specific requirements.
