Installation Notes

Verify engine application and OE spark plug specification before installation. Bosch 8132 is supplied with a preset gap, so do not adjust the gap on applications marked “Do Not Gap, Gap is Preset.” Use the correct torque procedure for the cylinder head material and inspect ignition coils, boots, and plug wells during service. For Mercedes-Benz applications, confirm the exact model year and engine code because several listings include notes such as optional fitment or sustained high-speed driving use.
