Detailed Product Features and Specifications

The Bosch YR7LPP332W spark plug features a standard ground electrode tip design with a single ground electrode made from copper, enhancing heat dissipation and electrical conductivity. The center electrode tip is platinum, supported by a nickel-yttrium and copper core, which improves wear resistance and ignition stability. The insulator is made of ceramic with a projected design to ensure proper spark gap and insulation. This spark plug has a manufacturer heat range of 7, suitable for the specified vehicle applications. The hex size is 16mm, and the spark plug length is approximately 3.08 inches, making it compatible with the OEM specifications of the listed vehicles.

About the OE Fine Wire Double Platinum Product Line

The Bosch OE Fine Wire Double Platinum line is designed to provide enhanced durability and consistent ignition performance through the use of fine wire platinum electrodes on both the center and ground electrodes. This design reduces electrode wear and maintains a stable spark over time, which is critical for maintaining engine efficiency and emissions compliance in modern vehicles such as Audi, Porsche, and Volkswagen models.

Applications and Common Issues Addressed

• Replacement for worn or fouled spark plugs in Audi A3 Quattro, Porsche Cayenne, Volkswagen R32, and other compatible models
• Helps resolve misfires and rough idling caused by degraded spark plugs
• Improves cold start performance and throttle response
• Reduces engine hesitation and improves fuel efficiency
• Supports stable ignition in 4-cycle engines with precise gap and heat range

Installation Notes and Tips

• Ensure the spark plug gap is set to the factory specification of 0.9mm before installation
• Use a 16mm spark plug socket for proper torque application
• Apply anti-seize compound sparingly on the threads if recommended by the vehicle manufacturer
• Torque to manufacturer specifications to avoid damage to the spark plug or cylinder head
• Replace spark plugs in sets of six for vehicles requiring multiple plugs, such as the Audi A3 Quattro
