Champion Iridium Spark Plug RC12WMPB4 - 9202

Description

The Champion Iridium Spark Plug RC12WMPB4 is a premium performance spark plug engineered for maximum durability, strong ignitability, and stable operation across a wide range of engine loads. Built with a fine-wire iridium center electrode and platinum ground electrode technology, it is designed to deliver a sharper spark focus for reliable combustion, improved ignition performance, and extended service life.

Champion Iridium plugs are built for drivers and equipment owners who want long-lasting performance without sacrificing ignition stability. The V-trimmed fine-wire center electrode and V-trimmed ground electrode help promote sharper spark focus, while the Heat-Active alloy allows the electrodes to reach optimal operating temperature quickly. This helps maintain dependable performance under varying load conditions and supports maximum plug life in automotive, marine, and recreational applications.
