{"product_id":"spiro-pro-10-4mm-spark-plug-wire-set","title":"Spiro Pro 10.4mm Spark Plug Wire Set","description":"The Taylor 409 Spiro Pro 10.4mm Spark Plug Wires are engineered as a heavy-duty solution for air-cooled Volkswagen Type 1 engines, particularly for high-performance applications. These wires go beyond standard replacements, featuring a substantial 10.4mm diameter that provides crucial insulation and RFI suppression for modern electronic ignition systems, high-output coils, and high-compression builds. They ensure that maximum spark energy is delivered to the plugs without loss due to thin insulation or high resistance.\n\nThe construction of the Taylor 409 series involves a three-layer design. It starts with an 8mm silicone wire core for energy transfer, followed by a high-strength woven fiberglass over-braid for structural integrity and heat resistance. The outer layer is a thick 10.4mm silicone jacket, offering protection against temperatures up to 600 degrees Fahrenheit, which is vital in the hot environment of a Type 1 VW engine. This construction helps eliminate cross-fire and voltage leaks, leading to faster starts, smoother idling, and improved throttle response.\n\nFitment is specifically for Volkswagen Type 1 based engines with standard upright cooling shrouds, including VW Beetles (1946-1979), Karmann Ghias (1956-1974), VW Things (1973-1974), and VW Buses\/Transporters (1950-1971) equipped with Type 1 engines. Custom applications like Dune Buggies, Sand Rails, Trikes, and Kit Cars utilizing a VW Type 1 engine are also compatible. However, these plug wires are not compatible with 1972-1979 Type 2s equipped with the Type 4 1700\/1800\/2000cc engine.\n\nIt is recommended to use specialized 10mm-11mm plastic wire separators or combs for proper organization and to prevent rubbing against engine tin. For optimal performance, pairing these wires with a high-output coil, such as those from Pertronix or MSD, is advised to fully utilize their insulation and low-resistance capabilities.","brand":"Taylor","offers":[{"title":"Default Title","offer_id":52663944282424,"sku":"9395","price":67.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687721898.jpg?v=1784331121","url":"https:\/\/store.motormia.co\/products\/spiro-pro-10-4mm-spark-plug-wire-set","provider":"MOTORMIA","version":"1.0","type":"link"}
