Product Details

This Bosch spark plug is engineered around double platinum construction, with platinum used at both the firing point and the ground electrode contact area. That layout helps limit electrode wear and supports stable performance over time. Bosch 8150 is a 4-cycle resistor spark plug with a copper core, fine wire center electrode, standard ground tip design, and a 16 mm hex size. It is a direct-fit ignition component for 2011 Porsche 911, 2007-2009 Porsche 911, and 2003-2006 Porsche Cayenne applications.

Bosch’s OE Fine Wire Double Platinum line focuses on original-equipment-style ignition requirements, combining durability and consistent spark characteristics for vehicles that call for a double platinum plug. For Porsche 911 and Porsche Cayenne owners searching for Bosch 8150 spark plug fitment, this part matches the listed OE-style application data.

Common Issues This Part Can Address

• Worn spark plug electrodes causing weak or inconsistent ignition
• Gap erosion that can affect firing stability over time
• Rough idle related to aged ignition components
• Misfire concerns tied to degraded spark plug performance
• Hard starting caused by worn plugs in the ignition system

Installation Notes

Verify the vehicle’s engine application and plug specification before installation. Check the pre-gap against the engine requirement and inspect the ignition system for wear, carbon tracking, or oil fouling before fitting Bosch 8150. Use proper spark plug service procedures and torque to the vehicle manufacturer’s specification.

Quality Assurance
