Why Would You Need the HSP Upper Coolant Tube?
The factory upper coolant tube is functional but lacks durability and aesthetic appeal. It can crack over time due to its construction, and it simply doesnt match the performance and visual standards of the L5P platform.
What Makes the HSP Upper Coolant Tube Different?
The HSP Upper Coolant Tube is precision-built from aluminum to prevent failures and add durability. The aluminum construction allows for powder coating in a range of colors and is topped with the HSP Diesel logo for a custom look. Slight precision bends ensure a perfect drop-in fit with factory components—no modifications required. Installation is quick and easy with basic tools and knowledge.
