This special 2-stroke spark plug is installed as standard equipment by leading motorcycle manufacturers.
The patented U-shape of the ground electrode creates a larger and hotter flame front, which ensures complete combustion and thus also eliminates excessive fouling and erratic starting caused by poor fuel mixtures. Due to the placement of the U-shaped groove in the ground electrode, it remains intact throughout the spark plug’s entire service life. The special coating also protects the spark plug from oil contamination and significantly extends its service life.
Breakdown of the short code:

DENSO Heat Range Overview:

29–32 high heat range (cold spark plug, for heavily modified engines)
Please select the appropriate spark plug from the drop-down menu.
Note: For official MFK approval, the ignition system must include a noise-suppressed component. These spark plugs are not noise-suppressed and must therefore be used in combination with a noise-suppressed spark plug connector when driving on public roads. Before purchasing, use the downloadable spark plug overview to check which type is best suited for your setup.
You can find alternative spark plugs and connection hardware for your ignition system in the accessories section.
