Bi-Hex
As modern engines become more efficient and compact, engine components such as Spark Plugs are required to become smaller too. Traditional spark plugs have been designed with a hexagonal socket style (see adjacent illustration). Newer vehicle designs have required Bosch to create a special Bi-Hex Socket. The Bi-Hex provides increased strength on compact spark plugs over the standard hexagonal design. Due to this unique design a specific long reach Bi-Hex spark plug socket is required. |
