Wehrli L5P Duramax Thermostat Housing - Sparkle Granny Smith

This is the Wehrli thermostat housing for your 2017-2025 6.6L Duramax truck. It's a direct replacement for the stock housing, but with a custom powder-coated finish to make your engine bay look a lot cleaner. If you're looking to dress up your L5P Duramax, this housing is a solid option.

The Sparkle Granny Smith powder coat is a unique finish that really stands out. It's designed to complement other WCFab upgrades, like their intake kits or intercooler piping, so you can build a cohesive look under the hood. It fits right in place of the original part, making the installation straightforward.
