HPI Savage X 13 Fin Engine Heatsink titanium finish HSA-027/T by 3Racing  [HSA-027/T]

Fin head cooler designed for Savage nitro engines

This fin-style engine heatsink is designed as a scale accessory for HPI Savage 21, Savage 25 and Savage X 13 models. The titanium-colour finish increases external surface area around the engine head to assist passive cooling on nitro setups.

Installation is simple for experienced nitro handlers: remove the existing cooling head or cap if required, position the heatsink over the head, and secure with the engine head mounting points or any supplied hardware. Always verify clearance with the carburettor, tuned pipe and nearby servos before tightening down.

Used during testing or extended sessions, the heatsink provides extra thermal stability rather than direct power gains: it helps moderate head temperatures so you can fine tune needle settings with more consistent readings.
