NGK IRIDIUM IX Spark Plugs

Spark plugs of the highest quality guaranteed by NGK!

Over 90% of Japanese motorcycles come factory-equipped with NGK products!

While spark plugs may seem like a minor component, their impact on fuel consumption, starting ability, and engine performance is enormous. Manufacturers have conducted extensive testing to find the optimal spark plug for each motorcycle model, which is why manufacturer specifications must be adhered to!

Advantages of Iridium IX spark plugs:

Optimal ignition and improved engine operation: no issues with faulty ignition or stalling.

Better acceleration due to a more responsive throttle.

Reduced fuel consumption.

More than doubled lifespan compared to standard spark plugs.

No fouling with stop-and-go traffic.

Excellent ignition behavior.

All spark plugs marked with an "R" have an integrated 5 kOhm resistor, which is only necessary if a 5 kOhm suppressor is not already present. Generally, 5 kOhm of suppression per cylinder is sufficient, while values above 10 kOhm may reduce spark ignition energy.

If you can't find the perfect spark plug for your motorcycle right away, look for it in the "My Bike" section (top navigation bar)!

IMPORTANT NOTE: Before purchasing (!) and before installation (!) of spark plugs, always ensure that the spark plugs you have chosen exactly match the specifications and requirements outlined in the manufacturer's manual! If you can't find the manual, contact your workshop or motorcycle manufacturer! Use only approved products and specifications for your motorcycle! Failure to comply with these instructions may result in serious damage to your motorcycle, for which we disclaim any liability and warranty rights in advance!
