These are the next generation in high-performance and racing ignition lead technology, as used by major race teams worldwide. Designed for all ignition systems, including very high-output aftermarket ignition systems, Eagle 10.5mm ignition leads deliver outstanding performance for both competition and street applications.

Eagle 10.5mm leads feature three layers of high-temperature silicone jackets, allowing them to carry secondary voltages in excess of 70,000 volts while emitting virtually zero RFI. This ensures compatibility with virtually all modern high-tech onboard computer systems.

From V8 Supercars to street cars, world-class rally and circuit racing, powerboat competition, taxi fleets, and even 5,500HP Top Fuel dragsters, Eagle ignition leads have earned the trust of professional racers and enthusiasts alike through proven performance, reliability, and durability.

Although we try to keep the most popular Eagle ignition lead sets in stock, it is impossible to carry every combination. Eagle manufactures lead sets in 9.0mm, 10.5mm, and 11.0mm cable sizes, available in Blue, Red, and Black, with numerous routing options including under exhaust manifold, over valve cover, and around valve cover configurations. Various spark plug boot styles, Standard Distributor (female cap posts), HEI (male cap posts), and MSD distributor boots are also available.
