914Rubber US Spec Front Side Marker Base Seal for Porsche 914 (All Years)
Keep your Porsche 914’s side marker lights weatherproof with the 914Rubber US Spec Front Side Marker Base Seal (part number 914.631.405.06), designed for all 914 models from 1970-76. This reproduction seal fits between the side marker base (914.631.409.00/406.00) and the fender, preventing water, dust, and debris from entering the assembly or front trunk. Two seals are required per car—one per side—ensuring a tight fit for US-spec amber or clear side markers (914.631.945.00/946.00).
PMB Performance, with over 20 years of Porsche 914 expertise, has partnered with 914Rubber for nearly two decades, selling more 914Rubber SKUs than any other retailer. Crafted from soft, high-quality neoprene, this seal improves on the factory design with a refined profile that conforms better to the lens and fender contours, unlike OEM seals that harden and crack. It withstands the 914’s fender exposure to road spray, temperatures up to 160°F, and UV radiation, maintaining flexibility for a durable, leak-proof seal.
A degraded seal allows moisture to infiltrate the side marker assembly, risking corrosion of the 5W bulb socket or wiring, which can cause flickering or failure in the 914’s 12V system. This can also lead to water seepage into the front trunk, potentially damaging the fuse box or stored items. This 914Rubber seal installs easily, compressing between the base and fender during mounting, and pairs perfectly with the 914.631.218.10 plug boot and 914.631.958.10 screws for a complete refresh.
