Wehrli L5P Duramax Thermostat Housing - WCFab Red

If you're working on your 2017-2025 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterparts, and want to clean up the look of your engine bay, this thermostat housing from Wehrli is a solid option. It's a direct replacement for the factory thermostat housing, meaning it bolts right up without any modifications needed.

This housing is powder coated in a vibrant red finish, which not only looks good but also complements other WCFab upgrades you might have, like their intake kit or intercooler piping. It's a simple way to dress up the engine compartment and make it stand out, especially if you're aiming for a cohesive look with other aftermarket cooling and intake components.
