3Racing HSA-027/B Blue Engine Heatsink 13 Fin for HPI Savage 21/25/X  [HSA-027/B]

Practical cooling solution for Savage engines

The 3Racing HSA-027/B heatsink features 13 fins in anodised blue to increase the cooling surface for HPI Savage 21/25/X engines. Its straightforward design helps lower head temperatures during heavy throttle runs and rough off-road sessions.

Aluminium fins to manage engine heat

Built from aluminium for reliable thermal transfer, the heatsink spreads heat away from the combustion chamber and into passing air. The fin density and shape are tuned to promote steady airflow and reduce the chance of overheating on long days at the track.

Made to fit Savage 21, 25 and X without mods

The heatsink is shaped to sit correctly on the factory head and fastens using the stock hardware. Installation is quick and keeps the unit secure under everyday running and jumps.
