• Unique housing, lid, and intercooler geometry was developed and optimized to distribute airflow evenly across the large, highly efficient intercooler for maximum cooling to deliver consistent air charge temperatures in even the most challenging driving conditions including hot temperatures and towing.
• Proven maintenance-free supercharger technology. No added complexity of external supercharger oil coolers/heaters for extreme climates.
• 3-year/36,000-mile Powertrain Warranty

• 2014-2018 GM Trucks with L83 5.3L Engine. Including the GMC Sierra, Chevrolet Silverado

Calibration is available for stock or modified vehicles. Modifications must be documented when submitting the Calibration File Form to Magnuson. For extreme builds, please contact our Sales Department to verify suitability for tuning in advance of purchasing the kit.

NOTE TO CUSTOMERS WITH MODIFIED VEHICLES: The Magnuson calibration included with this kit is intended to work on stock vehicle configurations, including stock trim levels and stock OEM vehicle options. Modifications to your stock vehicle include but are not limited to, engine, flywheel, clutch, torque converter, transmission, wheels, tires, axles, gears, driveshafts, induction system, exhaust system and additional weight (ie. bumpers, racks, etc.) can have a significant impact on your vehicle’s calibration and may require modifications to our calibration as supplied. While we attempt to minimize the need for modifications during our development process, it is impossible for our team to account for all possible build variations/combinations, and in some cases, it may be necessary for you to supply an additional element of customization for your vehicle—custom calibration—and to work, at your own direction and expense, with a local service facility to address your unique combination of hardware and make calibration adjustments as necessary. Please be aware that standard product warranties and governmental emissions certifications are predicated on stock vehicle configurations, and vehicle modifications and calibration changes may affect or even void powertrain warranty and emissions certification status (such as CARB emissions certification). It is the sole responsibility of the customer making a warranty claim to prove that any vehicle modifications and calibration changes were within warranty. It also is the sole responsibility of the customer to determine if the modifications and changes comply with all local, state, and federal emissions standards.
