Description
Enhanced Ignition Performance. These high-temp ignition wires and coil-pack internals deliver a stronger, more consistent spark to each cylinder, translating into quicker throttle response, smoother idle, and improved fuel burn. The spiral-wound core design maximizes voltage delivery while the silicone jacket resists heat soak under heavy load, ensuring reliable starts and power delivery even in extreme conditions.
Superior Thermal and Electrical Durability. Constructed from silicone insulated with a thick, abrasion-resistant jacket, these wires withstand under-hood temperatures up to 500°F without cracking or deforming. The precision-molded boots and upgraded insulator sleeves protect coil-packs from arcing and moisture intrusion, extending component life and maintaining optimal ignition timing.
Installation. Disconnect battery, remove factory wires one at a time to avoid mix-ups, attach the high-temp wire and boot to the spark plug and coil pack until fully seated, repeat for each cylinder, then reconnect battery and verify engine operation.
