spark plug Bosch W8AC (alt. B5HS) W8AC

Standard Bosch spark plug. This spark plug matches the heat value and construction of the original. Unlike the NGK BR5HS or Bosch WR8AC spark plugs, the W8AC 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.
