Savage Engine Heatsink 13-Fin Titanium HSA-027/TI by 3Racing  [HSA-027/TI]

Scale heatsink for Savage compatibility

This is a scale engine heatsink made for Savage-compatible models and marked with part code HSA-027/TI. The 13-fin, titanium-look construction creates a small but effective cooling area for nitro engine heads used in off-road trucks.

The component increases the head's exposed surface to improve passive heat dissipation, helping the engine hold a more consistent temperature while you tune or during extended running sessions. It is supplied as a model accessory only, not for real engine use.

Fitment advice: mount the heatsink onto the engine head where the model's original head screws and mounting points provide secure contact. Check for sufficient clearance under your bodyshell and make sure airflow is not blocked before final assembly. Extra mounting parts are not assumed to be included.

Tuning notes: correctly fitted, the heatsink can limit extreme temperature spikes and make idle and mid-range adjustments behave more consistently. Expect improved thermal control rather than a power increase.
