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

Exhaust-area thermal shield for R/C engines

This thermo insulator is an RC-scale engine accessory intended to manage heat transfer around model nitro engine components. It provides a thermal shield placed adjacent to hot zones to reduce heat soak into nearby parts during adjustments and servicing, without changing engine internals.

Fitment is broadly compatible with common R/C nitro layouts near the muffler or exhaust junction; always confirm the pad will clear surrounding linkages and body panels on your particular model. Mounting is a simple mechanical task using clamps or existing fasteners, and you should double-check airflow routes are not obstructed after installation.

Role in tuning: the insulator helps stabilise local temperatures which can make heat-based tuning steps more repeatable. It remains a passive accessory and must be used in combination with correct cooling setup and fuel adjustments for best results.
