Spark Plug - R0451B-8

The NGK Spark Plugs R0451B-8 is a high-performance iridium spark plug designed to support dependable ignition and efficient engine operation. Manufactured by NGK Spark Plugs, this plug uses an ultra-fine iridium center electrode to reduce the voltage required for ignition compared with conventional nickel designs. Its compact electrode profile helps promote a strong, consistent spark while reducing stress on ignition components.

Fitment: The R0451B-8 model is intended for applications that specify this exact plug design, heat range, reach, and electrode configuration. Confirm vehicle, engine, and manufacturer service specifications before installation to ensure proper fitment. The NGK Spark Plugs manufacturer part number and vendor part number are both 9356.

Performance: The iridium electrode is approximately 25% smaller than a platinum electrode and about one-quarter the size of a conventional nickel electrode. This ultra-small diameter center electrode helps lower ignition voltage requirements and may contribute to extended ignition system service life. The enhanced metal shell plating also provides improved resistance to corrosion, helping maintain durability in demanding operating environments.

Install the NGK Spark Plugs R0451B-8 according to the applicable manufacturer torque and service procedures. Avoid using this plug outside the engine applications and specifications for which it is recommended.
