상품 특징

• Specs: M12-1.25 thread, 26.5mm (1.043in) reach, 5/8in (16mm) hex, gasket/flat seat, projected insulator; pre-gap 0.028in (0.7mm); resistor 5000 ohm; heat range 9. Iridium fine-wire center tip + copper core helps deliver consistent spark and durability. Replaces/Interchanges: ILKR9Q7G / 97312.
• Install/replace: Work on a cold engine. Disconnect battery negative if required by your manual. Remove coil/boot, blow debris from the plug well, then remove the old plug with a 5/8in socket. Start threads by hand, then tighten to the torque spec in your service manual. Verify reach/seat type and gap before installing; do not over-tighten. Typical location: spark plug wells in the cylinder head (under coil/boot).
• Fitment verification: To avoid returns, confirm application by part number ILKR9Q7G / 97312 AND your vehicle service manual/catalog (engine code, thread, reach, seat type, heat range, and gap).

• Related maintenance: Replace spark plugs at the interval in your manual and inspect coils/boots and connectors if you have persistent misfire/rough idle. Worn plugs may contribute to hard starts, hesitation, reduced fuel economy, or a check-engine light, but other ignition/fuel issues can show similar symptoms.
• Fitment reminder: Use the part number ILKR9Q7G and your vehicle service manual/catalog to confirm application before ordering (model names and engine offerings can vary by market). Do not substitute if your engine requires a different reach, seat type, heat range, or gap.
• Related maintenance: Replace spark plugs at the service interval in your manual and consider servicing ignition coils/boots or connectors if you have persistent misfire/rough idle. Worn plugs can contribute to hard starts, hesitation, and reduced fuel economy, but other ignition/fuel issues may present similar symptoms.
