The Bosch W7AC is a genuine Bosch spark plug.A Bosch spark plug with a nickel-alloy centre electrode and copper core. The copper core carries heat away from the firing tip, letting the plug resist both fouling at low speed and overheating under load. Built to Bosch's original-equipment specification; easy to inspect and re-gap.Bosch heat value 7 (higher number = hotter plug on the Bosch scale). Approximate NGK equivalent heat range: 6.Heat (NGK scale) is our conversion of the Bosch heat number onto the NGK scale, so plugs from different makers can be compared on one hot-to-cold ladder. Makers' cross-references can be half a heat range apart, and plugs have moved up or down the scale over the years where no direct replacement exists, so treat it as a guide and check the recommendation for your vehicle.
