INSTALLATION INSTRUCTIONS

  • First, tighten the spark plug by hand until the piston rod touches the cylinder head. In case you have trouble tightening the spark plug by hand, use another tool such as a soft rubber hose to make the installation easier.
  • Limit the use of wrenches to install spark plugs on the original engine head because it is likely that the threaded part of the spark plug will be damaged if not careful.
