HPI Savage 21/25/X13 Fin Heatsink titanium style HSA-027/T by 3Racing  [HSA-027/T]

Fin-style heatsink for Savage nitro engines

This fin heatsink is a scale accessory made for HPI Savage 21, Savage 25 and Savage X 13 platforms. The titanium-colour finish fits over the engine head area to add passive cooling capacity for nitro-powered RC vehicles.

Fitting is straightforward for anyone used to nitro engine maintenance: remove the original cooling head or cap as needed, place the heatsink over the head, and secure using the head mounting points or any included parts. Always confirm clearance with the carburettor, exhaust and linkages prior to final tightening.

At the bench or on the track this part is intended as a thermal management aid rather than a performance modifier: it helps reduce head temperature swings during longer runs and provides a more stable baseline for tuning work.
