• Compatible with all Radium Fuel Rail Kits that originally came with thermal spacers when needed.

These press-fit spacers and washers are used with many Radium Engineering kits for thermally isolating the fuel rail from the engine.

• These are sold individually. Double check how many are required prior to purchasing.
• Spacer height measurement does not include press-fit insert length. Example: total height for 14-0711 Insulating Spacer, 11mm is 17.3mm.
• These can be used as replacements for Radium Engineering fuel rails that use phenolic spacers.
• Mounting hardware is not included. However, most bolts are common and can be sourced in local hardware stores.
