Performance Ignition Coil Wire for HEI Terminals Reliable, Fast Ignition: Designed to connect directly to HEIstyle terminals, this ignition coil wire efficiently delivers stable voltage current to the spark plug. It ensures precise ignition timing, improves power response, minimizes the risk of current leakage or poor contact, and supports smooth, consistent engine operation. SpaceSaving 90Degree Elbow Design: The 90degree elbow sheath provides a secure connection to the temperature ignition coil while saving space in your engine compartment. Ideal for vehicles with limited underhood clearance, it helps prevent wire damage and maintains routing even in tight spaces. Durable, Conductivity Construction: Features an internal carbon fiber conductor that offers conductivity and reduced resistance for improved performance. The outer insulating layer resists temperatures and aging for longlasting reliability. The vibrant red exterior makes identification quick and easy during maintenance, adding safety and convenience. Compatibility: Suitable for HEIstyle terminal systems. Direct replacement for part number 84059. Please verify compatibility with your vehicle's ignition system before . Applications: 1. Performance tuning upgrades where faster throttle response and consistent spark delivery are critical. 2. Routine replacement for worn or damaged ignition coil wires in HEIequipped vehicles. 3. Ideal for vehicles with compact or crowded engine bays where the 90degree sheath ensures secure fitment without interference.
