Iridium Spark Plug

The Champion 9201 is an iridium spark plug engineered for maximum performance and extended service life. It utilizes a fine-wire iridium center electrode, laser-locked for durability, and a platinum V-trimmed ground electrode to promote greater excitability and concentrated spark focus. This construction provides superior corrosion resistance and erosion resistance, making it suitable for various applications, including flex fuel and ethanol blends. Key specifications include a 14mm thread size with a 1.25mm pitch, a 0.75-inch (19mm) reach, and a 5/8-inch (16mm) hex size. The spark plug features a gasket seat type and a removable nut terminal. It is also designed as a resistor type for optimal electrical performance. This spark plug is a direct replacement for various applications, including specific models of Acura light trucks and passenger cars, as well as certain Toyota Corolla and Subaru Forester vehicles. It also crosses over to replace other manufacturers' part numbers such as Honda 9807B-561-5W, DENSO K20RU, DENSO SK16PR-A11, and NGK BKR6EYA.
