HPI Savage 21 Low-Profile Engine Heat Sink 13 fins SAV1815 by GPM  [SAV1815]

Low-profile alloy heat sink for Savage 21

The 13-fin low-profile alloy heat sink corresponds to model SAV1815 and is intended for use on HPI Savage 21 cylinder heads. The fin design increases surface area to aid heat dispersion during sustained running.

Fitment is targeted at HPI Savage 21 engines; confirm the head shape and mounting points on your model before purchasing. The heat sink is supplied as a single set and fits over the cylinder head without altering internal components.

Practical fitting tips: check body clearance, ensure the sink lines up with existing head fastenings, and use proper thread engagement on screws. Continue routine engine maintenance and monitor head temperatures on initial outings to validate cooling performance.

This aluminium 13-fin head sink is a direct aftermarket replacement to help passive cooling at the cylinder head for compatible Savage 21 engines; always confirm mechanical clearance before prolonged use.
