What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent ignition output
• Misfire conditions related to plug wear or incorrect gap
• Reduced throttle response from degraded spark quality
• Maintenance intervals on vehicles calling for iridium plugs

Installation Notes

• Confirm vehicle-specific fitment before ordering, especially on dual-plug or twin-spark applications.
• Check the listed gap for your exact year, make, and model; some applications require adjustment from the pre-gap setting.
• Use the correct torque procedure and inspect coil boots, wires, and ignition components during service.
• Verify thread reach, seat type, and hex size match the engine specification.
