BOSCH 6743 Platinum+4 Spark Plug - Pack of 10

Bosch Platinum+4 Spark Plugs deliver improved ignitability and fuel efficiency. The fine wire design with a platinum firing pin on the center electrode and tapered ground electrode are an economical upgrade from conventional copper core spark plugs. Nickel plated, rolled threads, combined with a factory preset gap, ensure simple, easy installation right out of the box - no anti-seize or gapping necessary. Engineered to meet or exceed Original Equipment specifications for platinum spark plugs.

• Bosch OE Fine Wire Platinum+4 Spark Plugs feature a specially engineered, yttrium enhanced ground electrodes that provides 2X longer service life compared to standard copper plugs
• Unique 360 degree, continuous laser welded platinum firing pin design delivers better corrosion resistance, ignitability, and performance
• Ribbed insulator design keeps flash-over causing oil, grime, and debris out of the spark plug wire or coil on plug boot, ensuring electrical energy goes into the spark plug - not around it - preventing misfire
• Nickel-plated rolled threads provide exceptional resistance to corrosion and do not require anti-seize - making installation quick and easy
• Bosch Platinum+4 Spark Plugs are pre-gapped at the factory and ready to install right out of the box - gap adjustment prior to installation not required
