What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent ignition firing
• Misfire symptoms related to degraded plug electrodes
• Reduced throttle response from weak spark delivery
• Maintenance replacement for vehicles using RN11YC4-equivalent plugs

Installation Notes

Verify plug type, thread diameter, reach, seat style, and pre-gap before installation. The pre-gap is listed at 0.041 in. / 1.05 mm, but final gap should always be checked against the vehicle service specification. Confirm the engine calls for a flat-seat, 14 mm spark plug with a 0.75 in. reach before installing Champion 322-1.
