FR91X Bosch Spark Plug Super 4 N60 (Pack of 4)

Specialist technology for even more efficient engines. Surface air gap principle with four ground electrodes - the optimum spark gap is always selected. Ground electrodes wear is evenly distributed over all four electrodes.

The silver-plated centre electrode ensures good heat dissipation and thus avoids the risk of autoignition due to overheating. Spark plug efficiency is enhanced by up to 40% increase in ignition energy.
