HPI Savage 21 Fin Engine Heatsink titanium finish HSA-027/T by 3Racing  [HSA-027/T]

Fin-style head cooler for HPI Savage nitro trucks

This fin-style engine heatsink is a scale accessory made to suit HPI Savage 21, Savage 25 and Savage X 13 platforms. The titanium-colour finish sits over the engine head and acts as an external cooling aid for nitro-powered setups.

Installation is user-friendly for those familiar with nitro engine work: remove the stock cooling head or cap where needed, slide the heatsink into position over the head, and secure it using the engine head mounting points or any supplied hardware. Always check clearances around the carburettor and surrounding components before final tightening.

Used on the bench or at the track, this part supports thermal management rather than replacing tuning work: it helps stabilise head temperature during longer runs and makes it easier to monitor engine behaviour under different conditions.
