The new design for the 17 piece end cap filter wrenches has been improved by adding welds to hold a steel disc to the top of the wrench. This is in addition to the spot welds which will greatly increase its strength. A collection for use on the most popular domestic and import vehicles. This set will also include the Toyota end cap 64 millimeter - 14 flutes, which has been improved by adding heat-treated steal to the drive area and adding two solid welds to the surface to increase strength.
