D-Shape outer electrode and ruthenium center electrode. As a 2-wheel dedicated spark plug, it improves the various performance of the spark plug (acceleration, durability, fouling resistance, fuel economy, startability, etc.).
The D-Shape outer electrode is an electrode shape that does not interfere with the flow of mixed air. Effectively guides mixture into spark gap
The D-Shape outer electrode is an electrode shape that does not interfere with the spread of flames. Achieves an ideal burn for a more spherical look
D-Shape outer electrode provides excellent ignitability.
Highly responsive acceleration
Improves fuel economy by improving combustion efficiency
Increased thermos clearance
Achieve a long life.
Compatible models: Super Cab 50 (AA04).
