Genuine Speed-Tec spare/option part.

Carburetor heat sink for all Zenoah / CY / HPI / Losi and PT-Smartech/Carson engines

Fits all 603/813/990/771/527/1107 Walbro carbs, all carbs on Smartech / Carson PT engines and many more!

The SPEED TEC Carburetor heat sink counteracts the notorious vapor lock at high engine temperatures.

In fact all current large scale engines have a special adaptor for the thermal insulation of the carb (insulator) to keep the carb as cool as possible, so that the fuel does not form bubbles due to heat transfer from the cylinder. And without this insulator the gasoline would literally cook after a short operating time and therefore the engine would receive a leaner mixture. The much feared lean-out until the engine stalls is inevitably.

At higher ambient temperatures, or under high loads, the engine, i.e. in racing even a special insulator (ST1014) will not work sufficiently. In this situation the additional heat dissipation of the SPEED TEC Carburetor heat sink often helps in solving the problem.

The easy-to-install heat sink fits easily to all current 1/5 & 1/6 large-scale cars such as FG, Smartech / Carson, HPI, Losi, etc.

For installation in FG 4WD - models the rear cross member # 66212 has to be modified.
