4 Bosch Platinum Iridium Evo Spark Plug for Benz GLA X156 GLB X247 GLC X253 SLC

Today's turbocharged gasoline direct injection engines place high demands on spark plugs. To meet these needs, the new Bosch EVO spark plug is engineered to ensure reliable ignition throughout its long service life - even under extreme conditions in modern engines.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.

Key Features :

• A laser-welded iridium alloy pin on the center electrode and a platinum-iridium alloy plate on the ground electrode ensures long service life and high wear resistance
• An improved insulator and housing design for increased head-bending strength reduces the chance for damage during installation and optimizes gas seal tightness in the cylinder head
• Increased thermomechanical, mechanical and electrical strength allows it to withstand extreme pressure during mega knocking
