FAQ:
Q: What kind of spark plugs does Bosch use?
A: Bosch guarantees you will feel improved performance in your vehicle when using any of Bosch OE Fine Wire Spark Plugs (Double Iridium, Double Iridium Pin-to-Pin, Double Platinum and Platinum).
Q: Is the Bosch spark plug void of warranty?
A: So, if the consumer is told that only the original equipment spark plug will not void the warranty, they should request the OE spark plug be provided free of charge. If they are charged for the spark plug, the manufacturer or dealer is in violation of the Magnuson-Moss Warranty Act. Are Bosch Spark Plugs pregapped at the factory?
Q: What makes Bosch Evo spark plugs so good?
A: Thanks to its improved insulator design and high dielectric strength (greater than 45 kV), the new EVO spark plugs can withstand irregular combustion – known as mega knocking – that can occur in modern, technologically advanced engines. Bosch EVO spark plugs are developed and produced with the same high quality as original equipment spark plugs.
Q: How do you tighten a Bosch spark plug?
A: Bosch recommends when installing spark plugs to use a torque wrench and the correct torque in ft.-lbs. If a torque wrench is not available, hand tighten the plug until it is seated in the cylinder head. Spark plugs with gaskets should be tightened an additional 90° while spark plugs with tapered seats should only be tightened an additional 15°.
