Installation Notes	Use 14mm x 17.5mm (.708”) reach tapered seat resistor type spark plugs. Heat range requirements will vary by application. For many applications, GM factory spark plugs or equivalent spark plugs such as Champion RS14YC6, NGK TR55, or Denso IT16 spark plugs may be used. Use anti-seize on the plug threads to prevent galling in the cylinder head, and torque to 10 ft./lbs. Do not over tighten sparkplugs! If a short reach plug is used, poor performance and possible engine damage may occur.
