The resistor design is rated at 6000 ohms, and the center electrode core uses nickel-yttrium and copper materials for stable performance. Bosch ZR6SPP302 is engineered as a 4-cycle spark plug for secondary ignition service where OE-style platinum construction is required.

Compatible With 2010-2015 Mini Cooper, 2011-2016 Mini Cooper Countryman, and 2013-2016 Mini Cooper Paceman. This part number, ZR6SPP302, is commonly searched for Mini Cooper spark plug replacement, Mini Cooper Countryman platinum spark plug replacement, and Mini Cooper Paceman OE fine wire platinum spark plug service.

What This Spark Plug Helps Address

  • Hard starting caused by worn spark plug electrodes
  • Misfires related to weak or inconsistent spark output
  • Rough idle from degraded ignition performance
  • Reduced fuel economy from inefficient combustion
  • Maintenance replacement for OE platinum spark plug service intervals

Installation Notes and Tips

ZR6SPP302 is supplied with a preset gap, so do not gap the plug before installation. Verify the engine application against the vehicle’s OE spark plug specification before service, and install using the correct torque procedure for the cylinder head material. For Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman applications, confirm the original plug type is platinum before replacement. The part number ZR6SPP302 should be matched to the engine’s required thread, reach, seat, and heat range.

Quality Assurance
