LS Thermostat Housing w/ 16AN Male Nipple Black

The LS Thermostat Housing with 16AN Male Nipple Black from Billet Specialties is a precision-engineered cooling system component designed for LS engine swaps and custom builds. This durable, high-flow alternative replaces the factory plastic thermostat cover, integrating seamlessly into modern LS engine configurations. Whether you're building a street machine, restomod, or high-performance track car, this thermostat housing serves as both a functional component and a visual upgrade.

Constructed from premium billet aluminum, this housing features a 16AN male nipple port that provides a clean, professional connection point for custom coolant lines and remote thermostat configurations. The 16AN fitting standard allows for flexible hose routing without the restrictions of factory coolant passages, enabling builders to optimize cooling flow paths for improved thermal management. The billet construction eliminates the plastic failure points common in stock housings, while the black finish resists corrosion and maintains its appearance in engine bays exposed to heat cycles and road conditions.

Enthusiasts and professional builders choose this Billet Specialties thermostat housing for LS1, LS2, LS3, and LSx engine conversions. Its compact design integrates efficiently with LS engine bay layouts without compromising accessibility. This product is ideal for those looking to enhance their cooling systems while ensuring reliability and performance.
