FEATURE

  • Bosch EVO spark plugs are engineered to deliver maximum ignition performance within the extreme combustion environment that is the hallmark of modern turbocharged engines with gasoline direct injection
  • Turbocharged gasoline direct injected engines place high mechanical and performance demands on spark plugs, due to extreme combustion pressures and irregular combustion, known as mega knocking, that can occur
  • Bosch EVO spark plugs feature increased thermomechanical, mechanical and electrical strength that ensures they will withstand the extreme pressures generated during mega knocking
  • EVO spark plugs incorporate an improved insulator and housing design for increased head-bending strength that reduces the chance for damage during installation and optimizes gas seal tightness in the cylinder head
  • With a laser-welded iridium alloy pin on the center electrode, and a platinum-iridium alloy plate on the ground electrode, EVO delivers a long service life and high wear resistance


DESCRIPTION

Modern turbocharged gasoline direct injection engines place high demands on spark plugs. Bosch EVO spark plugs are engineered for maximum ignition performance in turbocharged engines with direct gasoline injection (GDI). Thanks to its improved insulator design and high dielectric strength, the new EVO spark plugs can withstand irregular combustion – known as mega knocking – that can occur in today’s technologically advanced engines. Bosch EVO spark plugs are engineered and manufactured to the same high quality standards Bosch spark plugs - both original equipment and aftermarket replacement - are known for.
