3Racing HSA-027/P purple heatsink fits the HPI Savage 25 and uses 13 fins to improve thermal dispersion. It is suited to long runs and mixed terrain use where consistent cooling matters.
The fin geometry increases surface contact with air so heat moves away from the head more effectively. You will notice more stable engine temps during repeated runs.
Finished in purple, the heatsink offers a distinctive appearance while being made to resist everyday wear from trail and track use. It is a straightforward upgrade for hobbyists wanting both style and function.
