Radium Engineering Insulating Spacers & Washers (Injectors)
Radium Engineering builds precision fuel system hardware for serious motorsport and high performance applications, and these insulating spacers and washers are a simple but effective fix for injector heat soak. They reduce thermal transfer from the engine to the fuel injectors while providing electrical isolation, helping maintain consistent spray patterns under sustained heat load.
This listing covers the injector insulating spacer range, available in 11mm, 15mm, 20mm and 27mm sizes plus an M8 insulating washer, selectable via the variant options on this page. Match the size to your fuel rail and injector configuration before ordering.
