This design reduces electrode wear and maintains stable ignition over extended service intervals, making it suitable for modern 4-cycle engines requiring precise ignition components.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThe Bosch 9687 spark plug features a fine wire iridium center electrode supported by a copper core, which improves heat transfer and ignition reliability. The ground electrode uses a durable iridium-platinum tip with a standard design and J-gap configuration, ensuring consistent spark generation. The ceramic insulator is projected and designed to withstand high temperatures while maintaining electrical insulation. With a pre-gap size of 0.8 mm and a flat seat, this spark plug fits securely in the combustion chamber. The integrated 6000 ohm resistor helps suppress electromagnetic interference, protecting sensitive vehicle electronics.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Common Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement spark plug for Mitsubishi Eclipse, Endeavor, and Galant models\u003c\/li\u003e\n\u003cli\u003eSuitable for Toyota Prius C ignition systems\u003c\/li\u003e\n\u003cli\u003eAddresses issues such as misfires, rough idling, and poor fuel economy\u003c\/li\u003e\n\u003cli\u003eHelps reduce engine hesitation and improves cold start performance\u003c\/li\u003e\n\u003cli\u003eSupports stable combustion in 4-cycle engines requiring iridium spark plugs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the spark plug gap is set to the manufacturer’s recommended specification before installation, although the Bosch 9687 comes pre-gapped at 0.8 mm. Use a 16 mm socket wrench for proper tightening torque to avoid damage to the spark plug or cylinder head. Inspect the spark plug threads and seat type compatibility with your vehicle’s engine to confirm fitment. Avoid over-tightening to maintain the integrity of the flat seat design.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eBosch OE Fine Wire Double Iridium spark plugs are manufactured to meet strict quality standards for durability and performance.
