Bosch FR8DPP33 OE Fine Wire Double Platinum Spark Plug

The Bosch FR8DPP33 OE Fine Wire Double Platinum Spark Plug is engineered to deliver reliable, consistent ignition performance meeting original equipment standards. Featuring platinum on both the center and ground electrodes, this plug provides outstanding ignition reliability and long-term wear resistance across its full service life.

Key Features:

• Double Platinum Electrodes: Platinum-tipped center and ground electrodes ensure superior durability and consistent spark performance over an extended service life
• Fine Wire Center Electrode: Ultra-thin 0.6mm center electrode requires lower ignition voltage while delivering higher-energy ignition sparks for more complete combustion
• Copper Core Construction: Provides a broader heat range to effectively resist pre-ignition and fouling under varying engine loads
• Nickel-Plated Rolled Threads: Offers complete anti-seize and corrosion protection for easier installation and removal
• Angled, Ribbed Insulator Design: Prevents misfire caused by flash-over, ensuring reliable ignition in all conditions
