Modern day spark and glow plugs are built to exacting tolerances as are the engines they are fitted to.
Over torque the plug and this can lead to stretched threads, incorrect air gaps, broken inductance coils or ceramics, incorrect positioning of spark in the cylinder and ultimately to a poorly performing or even damaged engine.
The SX0371 prevents over-tightening of spark plugs and glow plugs and ensures garages are protected from hefty claims from customers at one end and refused warranty by the plug maker at the other.
Use in conjunction with your own plug sockets.
Supplied in storage case.
