Bosch ZR6SPP302 OE Fine Wire Platinum Spark Plug

The Bosch ZR6SPP302 OE Fine Wire Platinum Spark Plug delivers Original Equipment quality performance with enhanced ignitability and fuel efficiency. This premium spark plug features a pure platinum center electrode that is heat-fused into an extended ceramic insulator, eliminating air gaps found in platinum alloy-tipped plugs for superior reliability and longevity.

Key Features:

• Fine wire design with platinum firing pin on center electrode and tapered ground electrode
• 12mm x 1.25mm thread with 26.5mm (1.04") reach and flat seat design
• Heat range 6 for optimal thermal performance
• Factory pre-set 1.0mm (.039") gap - no adjustment required
• Nickel-plated rolled threads for easy installation
• Projected tip design for improved cold weather starting
• V-profile ground electrode enhances fuel ignitibility

This spark plug reaches its self-cleaning temperature faster than conventional copper core plugs, providing quicker starts, smoother acceleration, and improved fuel efficiency. Engineered to meet or exceed OE specifications with up to 2X longer service life than standard plugs. The lower ignition voltage requirement ensures reliable starting in extreme weather conditions and provides consistent spark at higher RPMs without misfires.
