Spark Plug DENSO SXU22HDR8 (3441)

The DENSO Iridium Tough SXU22HDR8 spark plug (part number 3441) is a high-performance component that combines the advantages of a 0.4 mm iridium center electrode and a platinum tip on the ground electrode. This design ensures stable spark formation under extreme loads and significantly extends the service interval up to 100,000 km. Technical parameters include a 12 mm thread diameter, 26.5 mm thread length, and a 16 mm hex size, which is typical for modern long-reach thread engines. This model is widely used in Honda, Mitsubishi, and Mazda vehicles, providing improved acceleration dynamics and reduced fuel consumption. The use of precious metals minimizes the voltage required for the spark gap, facilitating engine starting in low-temperature conditions. The product meets the highest OEM quality standards and serves as a reliable replacement for original equipment in ignition systems with high combustion efficiency requirements.
