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 AMSOIL EAO17 oil filter


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.

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.

2017-19 vs 20-23 Oil Cooler 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.
