Detailed Product Description

The Bosch OE Fine Wire Double Platinum spark plug 7432 features a fine wire design with platinum tips on both the center and ground electrodes, enhancing wear resistance and maintaining a stable spark over time. The center electrode core combines nickel-yttrium and copper materials, while the ground electrode core is copper-based, promoting excellent electrical conductivity and heat dissipation. The spark plug includes a 6000 ohm resistor to minimize radio frequency interference, protecting sensitive electronic components in Porsche Cayenne, Macan, and Panamera models.

This spark plug has a flat seat type and a thread diameter of 14 mm with a reach of 26.5 mm, matching OEM specifications for proper fit and sealing. The ceramic insulator is non-projected, providing reliable insulation and heat resistance. With a manufacturer heat range of 5 and a pre-gap size of 0.7 mm, this spark plug balances heat dissipation and ignition performance for 4-cycle engines.
