Savage 25 13-Fin Engine Cooling Head HSA-027/P for HPI by 3Racing  [HSA-027/P]

Product Brief

A dedicated RC engine heatsink tailored for HPI Savage 25 chassis use. The 13-fin profile increases external surface area to help shed heat from nitro engine heads while retaining a scale look.

The component increases thermal capacity and fin exposure, which typically slows warm-up and reduces sudden temperature spikes under continuous load. This behaviour makes it useful when fine tuning carburettor settings or testing body airflow effects.

Fitting is straightforward for experienced builders: remove the original cooling head, check clearance to the carburettor and headstack, then install the heatsink on the engine head. Check for any interference with the exhaust or surrounding parts and ensure secure seating before operation. Run-in at low revs first to confirm clearances.

Compatibility: designed specifically for Savage 25 series heads, so confirm your head dimensions before buying. Intended for nitro RC engines and model use only.
