Spark Plug Wire Set, Taylor, 409 Spiro-Pro 10.4mm, Race Fit, 135° Boot, LS

GM LS 409 Spiro-Pro 10.4mm Spark Plug Wire Set (135°) by Taylor Cable®

10.4mm silicone-insulated 409 wires pair spiral-wound suppression conductors with locking terminals.

Taylor Cable® 409 Spiro-Pro wires combine a spiral-wound suppression conductor with silicone insulation and a 10.4mm outer diameter for street and competition engine compartments. The insulation supplies continuous heat protection while remaining flexible for routing. RFI/EMI suppression helps protect radios and ignition electronics from interference, including installations using multiple-spark-discharge ignition. Low-profile silicone boots and double spring-lock spark-plug terminals provide secure contact under vibration. The engine-specific Race Fit plug leads are cut to length and booted for the routing configuration; check exhaust clearance before installation.
