Wehrli L5P Duramax Thermostat Housing - Sparkle Copper

When you're upgrading your 6.6L Duramax L5P engine, the details matter. This thermostat housing from Wehrli is a direct replacement for your factory part, offering a much cleaner look in the engine bay. It's designed to perfectly complement other WCFab upgrades, like their upper coolant pipes, giving your engine compartment a cohesive, well-built appearance.

This housing comes finished in a Sparkle Copper powder coat, which not only looks sharp but also helps protect the metal. It's a simple swap that makes a notable difference in how your engine bay presents itself, especially when paired with other WCFab components. If you're looking to tidy up the area around your cooling system, this is a solid option.
