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

Engine heatsink for Savage

This is an RC-scale engine heatsink designed for Savage model compatibility, carrying the 3Racing part code HSA-027/TI. The unit uses a 13-fin profile and a titanium finish to provide a compact cooling surface for small nitro engine heads used in RC trucks.

The heatsink's role is straightforward: increase exposed surface area to help transfer heat away from the engine head and support more consistent temperature behaviour during tuning and extended runs. Because it is a scale accessory, it is intended for model use only and not for any real vehicle application.

Installation notes: this heatsink is intended to be fitted to the engine head area of compatible Savage models, using the model's existing head mounting points and hardware. Check clearance inside the vehicle's body or chassis and ensure proper alignment with cooling airflow before securing. No additional tools or fittings are assumed to be supplied.

Tuning impact: when applied correctly the heatsink can reduce peak head temperature swings and contribute to steadier idle and running conditions during adjustments to needle settings or when testing fuel mixtures. It is a simple hop-up aimed at thermal management rather than power increase.
