914Rubber Side Marker Plug Boot for US Spec Porsche 914
Safeguard your Porsche 914’s side marker lights with the 914Rubber Side Marker Plug Boot (part number 914.631.218.10), designed for US-spec 914 models from 1970-76. This reproduction silicone boot protects the electrical connector at the back of the side marker housing, preventing corrosion and moisture ingress in the 914’s 12V system. Two boots are required per car—one per side—for the 5W amber or clear side marker lights (914.631.945.00/946.00).
PMB Performance, with over 20 years of Porsche 914 expertise, has partnered with 914Rubber for nearly two decades, stocking more 914Rubber SKUs than any other retailer. Crafted from high-temperature silicone, this boot withstands the 914’s exterior exposure to road spray, temperatures up to 160°F, and UV radiation, unlike factory boots that crack or harden. Its 8mm inner diameter ensures a tight, weatherproof seal around the connector, maintaining reliable operation of the side marker circuit, which ties into the 914.612.051.10 wiring harness.
Side marker lights, mounted on the 914’s fenders, are prone to water and debris infiltration, especially in wet climates. A degraded boot can lead to flickering, bulb failure, or shorts that strain the flasher relay or fuse box. This 914Rubber boot installs easily, slipping over the connector to shield the 914.631.409.00/406.00 base, and pairs with the 914.631.957.10 seal for a complete refresh. Regular checks during bulb replacement prevent electrical gremlins.
