Tamiya 41086 FR-32FX Compact Heat Sink Glow Engine  [41086]

Compact cooling with the Tamiya 41086 FR-32FX

The Tamiya 41086 FR-32FX Glow Engine with Aluminum Heat Sink Head is built for modelers who value straightforward, effective upgrades. First shown at the Shizuoka Hobby Show, this component is aimed at improving thermal control without complicating installation.

What the FR-32FX Brings to Your Model

The FR-32FX is a purposeful enhancement from Tamiya. The bright blue aluminium head lowers mass and promotes better airflow around the combustion chamber, helping the engine maintain steady operating temperatures under load.

Thermal Efficiency and Reduced Mass

Because the heat sink head is lighter than heavier cast heads, it reduces rotating and reciprocating mass slightly while improving heat dispersion. That combination is useful for longer runs and for keeping consistent performance across heats.

Options and Compatibility Overview

This head is offered both as a standalone replacement and within FR32-FX engine assemblies, making it easy to upgrade existing engines. Confirm fitment and clearance with your chassis before fitting to avoid interference with bodywork or cooling ducts.

For those tuning performance models, the Tamiya 41086 FR-32FX is a sensible upgrade to help keep temperatures down while trimming a bit of weight.
