Tamiya 41073 - FS12S Blue Aluminum Engine Heat Sink  [41073]

Optimized Cooling for FS12S Powerplants

This blue anodized aluminum heat sink is made for FS12S size engines and delivers improved thermal performance through a dense fin layout. With over three times the fin count of typical sinks and more than 1.5 times the surface area, it helps move heat away from the head so the engine stays cooler under load.

Low Profile Body Compatibility

The slim, low profile of this heat sink lets it sit neatly beneath shallow shells such as the Ferrari F430 without forcing body modifications. That makes it a practical upgrade for modelers who need added cooling but want to keep the factory look intact.
