Tamiya F350 HILUX 13 Fin Engine Heatsink by 3Racing HSA-027/BU  [HSA-027/BU]

Heatsink for Savage F350 Engines

The 3Racing HSA-027/BU is a purpose-built RC-scale heatsink shaped for the Tamiya F350 HILUX 13-fin head pattern and labeled for Savage use. It is intended as a drop-in cooling aid for model nitro engines where the fin count and profile match the F350 pattern, and it is supplied in a blue finish.

Installation follows common RC engine procedures: remove the existing cooling head, fit the heatsink over the engine head, and secure using the engine's existing head screws. No additional tools or modifications to the chassis should be required beyond standard engine access on Savage variants.

In tuning terms the heatsink's role is straightforward — increase the surface area exposed to air, lower head temperatures under sustained high-RPM runs, and provide a more stable baseline when adjusting needle settings or testing different fuels. It is not a performance part that increases power, but a thermal management component to support consistent engine behavior during bench testing and track sessions.
