The Wehrli L5P Duramax thermostat housing is a direct replacement for 2017–2025 6.6L Duramax applications, finished in Deore gold powder coat to dress up the engine bay and match other WCFab upgrades. It installs in place of the OEM housing with no modification and is offered in multiple powder-coat colors so you can coordinate with intake kits, intercooler piping, upper coolant pipe and coolant tank for a refined engine-bay finish.
