APR Iridium Pro Spark Plugs (4pcs)

Designed specifically for high-performance and modified engines, APR Iridium Pro Spark Plugs offer a premium alternative to standard factory components. By utilizing Iridium—an exceptionally durable material with a high melting point—these plugs are engineered to withstand extreme cylinder temperatures and pressures. The inclusion of a copper core further enhances heat dissipation, protecting the electrode from the cracking or melting often seen in lesser materials. Because they require less voltage to generate a powerful spark and operate at a cooler heat range, they are the ideal solution for tuned vehicles running high boost levels.
