spark plug Bosch W5AC (alt. B7HS) W5AC
Standard Bosch spark plug. This spark plug matches the heat value and construction of the original. Unlike the NGK BR7HS or Bosch WR5AC spark plugs, the W5AC is unshielded. This has no effect on the operation of the spark plug or the engine. However, under certain circumstances, electronic aftermarket parts, such as digital rev counters, could malfunction.
