13‑fin engine heatsink for Savage X

The HPI Savage X 13-fin engine heatsink supplied by 3Racing (HSA-027/RE) is an RC-scale cooling accessory designed for the Savage X platform. It places emphasis on fit and thermal management role rather than altering engine internals.

This heatsink uses a multi‑fin profile to increase exposed surface area, helping dissipate heat from the engine head during extended running or tuning sessions. The component is intended to replace or upgrade the stock head fins while keeping the chassis and mounting geometry unchanged.

Installation is straightforward for common Savage X setups: the heatsink aligns with the engine head and uses the engine's existing mounting points. Before finalizing fitment check clearances with the body, air filter and nearby components, and confirm that the fins do not contact moving parts.

In tuning terms, adding or changing a heatsink is part of temperature management: a different heatsink affects how quickly the engine sheds heat between runs, which can influence needle settings and run durations. Adjust tuning only after verifying operating temperatures under typical running conditions.

Compatibility
