Specifications
At the heart of the new system is GM's 2020 Duramax L5P oil cooler. This cooler rejects heat 22% better at the factory-rated 450 horsepower when tested against the earlier 2017-2019 unit. The difference between the two coolers is even more apparent at higher engine speed and load. 3300 RPM, 600 HP tests show a 31% greater heat reduction over the stock 2017-2019 oil cooler. The higher the horsepower, the greater the improvement.
Key Features
- Cools 31% or better
- More cooling plates for better heat rejection
- Increased cooling stack surface area
- Pre-installed 1/8-inch NPT sensor port for temp or pressure
- Includes all hardware
- Includes Baldwin B40150 oil filter

Enhanced Cooling for Extended Towing
At the factory-rated 450 horsepower output, the upgraded 19-plate cooler rejects heat 22% better compared to earlier 2017-2019 OE 14-plate oil coolers.
Tuned to 600 horsepower with a higher rpm speed and load, the difference between the two coolers is even larger, with 31% greater heat rejection.
Heat rejection gains are even more impressive on older Duramax engines, which use 10 or 11-plate factory coolers from 01-07 or 11-16 models.
These additional cooling plates and improved oil flow increases the available surface area utilized for heat transfer, shedding more BTUs of heat while maintaining proper oil pressure.
Banks chose the Baldwin B40150 oil filter for its superior filtration properties and pressure retention with an Anti-Drainback and 25 PSID Bypass Valve.
Exceeds OEM filtration specs:
99.8% efficiency @ 30 microns
99.1% efficiency @ 25 microns
94.2% efficiency @ 20 microns
