20238 8mm Pro Wire spark plug wire set. Red

These Taylor 8mm Spiro-Pro spark plug wires are a solid upgrade for 2017 to 2025 Touring and Trike models, though they are not compatible with the newer CVO or specific 2024-2025 Road Glide and Street Glide variants. Sold as a set of four, these red wires feature a spiral-wound core with 350 ohms of resistance per foot, providing excellent RFI suppression for modern multi-spark ignitions. The two-layer silicone jacket and low-profile ProBoots are built to handle high engine heat, while the double spring locking terminals ensure they stay seated despite heavy vibration. The set includes specific lengths for front and rear cylinders with a mix of 90-degree and 135-degree boots. Always check your aftermarket ignition manual, as some electronic modules prefer suppression core cables over spiral wound designs.
