Banks 13252 Improved Duramax Engine Oil Cooler Kit 2001+

This kit converts your early Duramax to a 2020+ L5P engine oil cooler. We use this kit quite regularly in the shop as well as in our engine builds.

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.

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
