NGK spark plug Iridium CR9EI-X/CR9EIX

NGK IRIDIUM IX SPARK PLUGS

• Guaranteed top quality with NGK spark plugs!
• Over 90% of all Japanese motorcycles are factory-fitted with NGK spark plugs!
• Although a spark plug may seem inconspicuous, its impact on fuel consumption, starting ability, and engine performance is significant. Vehicle manufacturers have determined the optimal spark plug for your bike through extensive testing procedures. Therefore, always adhere to the manufacturer's specifications.

Advantages of Iridium IX spark plugs

• optimal ignition and smooth running engine - so no ignition misfires or misfiring
• better acceleration due to faster throttle response
• lower fuel consumption
• at least double the lifespan of standard spark plugs
• no soot formation in stop-and-go traffic
• excellent starting properties

• All spark plugs marked "R" have an integrated 5 kOhm interference suppression resistor, which is only required if 5 kOhm suppression plugs are not already in use. A total of 5 kOhms per cylinder is sufficient for interference suppression. Above 10 kOhms, the spark ignition energy can be reduced.

• IMPORTANT NOTE: Before (!) purchasing and before (!) installing spark plugs, always check that the spark plugs you've selected exactly meet the specifications and approvals listed in the manufacturer's owner's manual! If you don't have the owner's manual handy, contact your motorcycle dealership or engine manufacturer. Use only products and specifications approved for your vehicle. Failure to comply can cause serious damage to your vehicle, for which we disclaim all liability and warranty.
