O.S. Engine OS28169460 Thermo Insulator Pad for GT15 R/C Nitro Engines  [OS28169460]

Thermal barrier for model nitro engines

This thermo insulator is an RC-scale engine accessory intended to manage heat transfer around model nitro engine components. It acts as a local thermal shield placed close to heat sources to help keep surrounding parts more stable during tuning and maintenance, without requiring internal engine changes.

The part is suitable for general R/C nitro engine arrangements near mufflers and exhaust ports; always check the pad's dimensions against your engine and exhaust route to ensure correct clearance. Fitting is typically mechanical, using existing mounts or ties; confirm that movement and airflow are not impeded once installed.

As a tuning aid, the insulator reduces rapid heat transfer to adjacent parts, which can make temperature readings and repeat adjustments more consistent. It does not alter engine timing or fuel delivery and should be combined with standard cooling and tuning practices.
