PPE Internal Oil Cooler Delete Kit 01-16 GM 6.6L Duramax LB7/LLY/LBZ/LMM/LML

For high performance GM 6.6L Duramax builds, PPE’s Internal Oil Cooler Delete Kit is the ultimate upgrade for better oil cooling and reliability.

Designed for marine applications, high horsepower builds, or hot rod setups with limited space, this kit eliminates the restrictive factory oil cooler, allowing you to run a much larger, more efficient external oil cooler. Machined from billet aluminum and finished with a hard-anodized black coating, this delete kit is built for durability and performance. The easy bolt-on adapter uses your existing factory oil-cooler mounting bolts, making installation straight forward. With #12 ORB x -16AN (1") oil inlet/outlets, it ensures maximum flow for improved oil cooling efficiency. Plus, the 1/8-inch NPT oil temp sender port allows you to monitor the oil temperature entering the block, keeping a close eye on engine performance. This kit also includes an Engine Coolant Bypass Adapter to maintain proper cooling system function. For the best results, pair it with a remote oil filter mount and PPE’s Coolant Tube Kit, and use -16AN 1" hoses to maximize flow.

Whether you're building a high performance Duramax race truck, marine setup, or custom hot rod, the PPE Internal Oil Cooler Delete Kit gives you the cooling capacity and reliability you need to push your engine to the limit. Upgrade today and experience the benefits of better oil flow, reduced restriction, and superior cooling performance.
