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. At higher engine speed and load, the difference between the two coolers is even more apparent. 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.

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.

*Due to Enhanced EGR cooling, Kit does not fit late 2007.5-10 LMM Duramax Engines
