Description
aFe Oil Pan – 2020–2025 GM Diesel 6.6L Diesel (L5P) Engine support engine lubrication and temperature management during sustained load. This listing is built around aFe POWER part number 46-71370B for the 2020–2025 GM Diesel 6.6L Diesel (L5P) Engine.
Oil carries heat while maintaining the film that protects bearings, valvetrain and other loaded surfaces. Capacity, baffling, cooling area and plumbing all affect how stable that system remains during hard use.
What This Means on the Car
For track, towing or high-output use, oil-system consistency is reliability hardware. The goal is not a cosmetic engine-bay change; it is maintaining pressure, temperature and serviceability as load rises.
Fitment & Part Numbers
Application: 2020–2025 GM Diesel 6.6L Diesel (L5P) Engine
aFe POWER part number: 46-71370B
Fitment can differ by engine, drivetrain, trim, factory equipment, emissions configuration and production date. Match the part number above to the vehicle before installation; where aFe publishes SKU-specific installation or emissions requirements, those requirements take precedence.
Legacy Racing Enthusiast Perspective
We prioritize oil-system upgrades when the use case exposes a factory limitation—temperature, capacity or control. Exact capacity and installation requirements should be matched to the SKU. On the 2020–2025 GM Diesel 6.6L Diesel (L5P) Engine, we would make the purchase decision around the limitation this component addresses and how it fits with the car's current and planned modifications.
