Year Make Model Engine
2017-2019 GM/Chevrolet Silverado/Sierra 2500HD/3500HD 6.6L Duramax L5P

This Max-Flow kit replaces the factory oil cooler on the 2017-2019 L5P Duramax with an oversized unit that adds up to 89% more cooling surface area and improved internal fluid dynamics for better heat rejection. It's a bolt-on swap, and in DmaxStore's testing it dropped oil temps 10-15 degrees during daily unloaded driving and up to 25 degrees at peak while towing up a grade. If your oil temps climb under load, this is a straightforward fix.
