Plugs & Leads

Ignition system plugs and leads are crucial components in performance vehicles, designed to ensure efficient and reliable spark delivery for optimal engine performance. Spark plugs are responsible for igniting the air-fuel mixture within the combustion chamber, and high-performance variants are typically made from advanced materials such as iridium or platinum. These materials offer superior conductivity and durability compared to standard plugs, allowing for a more potent and reliable spark. The fine-wire electrodes on performance spark plugs create a concentrated spark, improving ignition efficiency and combustion, which is essential for high-revving engines.

Ignition leads, also known as spark plug wires, connect the ignition coil or distributor to the spark plugs, transmitting the high-voltage current necessary for spark generation. In performance vehicles, these leads are constructed from low-resistance core materials such as spiral-wound copper or silicone, which minimise energy loss and ensure maximum voltage delivery to the spark plugs. High-performance ignition leads are also designed with advanced insulation materials to withstand the high temperatures and harsh conditions found in performance engines, reducing the risk of electromagnetic interference and ensuring consistent ignition timing.

The combination of high-quality spark plugs and ignition leads is essential for achieving reliable ignition and optimal engine performance. The precise and powerful spark provided by performance spark plugs, coupled with the efficient voltage transmission of high-performance ignition leads, ensures complete and efficient combustion of the air-fuel mixture. This results in improved power output, better throttle response, and increased fuel efficiency. Additionally, the durability and advanced materials used in these components reduce maintenance requirements and enhance the overall reliability of the ignition system in high-performance vehicles.
