Includes Bladwin B40150 oil filter

Specs
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.

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 increase the available surface area utilized for heat transfer, shedding more BTUs of heat while maintaining proper oil pressure.

Fits all 2001-2007 and 2011-2019 Duramax engines* Hardware, gaskets, and a Baldwin B40150 oil filter are included as well as a pre-installed 1/8” NPT port for oil temperature/pressure sensors.
