How do these NGK plugs affect engine starting and throttle response?

Proper, undamaged spark plugs contribute to reliable starts and steady combustion, which supports consistent throttle feel and engine idle. Replacing worn or fouled plugs with the correct NGK electrodes helps restore spark energy and reduces misfire risk under load. They don’t change engine tuning—only restore designed ignition performance.

• Restores manufacturer-intended spark characteristics
• Helps reduce misfires and rough idles when old plugs are replaced
• Supports consistent throttle response under typical riding conditions

What are the installation and torque recommendations?

Install each plug by hand until finger-tight to avoid cross-threading, then torque to the vehicle manufacturer’s specification. Use a calibrated torque wrench and inspect the gasket/washer for proper seating. Always replace plugs one at a time to preserve correct gap and orientation, unless performing a full engine service.

• Hand-start each plug to avoid cross-threading
• Tighten to Can-Am specified torque in the service manual
• Replace one plug at a time to maintain correct firing order

How will I know when to replace these spark plugs again?

Inspect spark plugs at regular service intervals or whenever performance issues appear, such as hard starting or inconsistent idle. Signs of heavy carbon buildup, electrode erosion, or damaged insulation indicate replacement. Lifespan depends on riding conditions and tune; check your service schedule for recommended intervals.

• Visual inspection for carbon, oil, or electrode wear
• Replace if engine exhibits misfires or poor starting
• Follow Can-Am maintenance interval guidance for routine swaps
