tightening torques

Dear Sir or Madam,
please be advised that the installation of the spark plug must be performed with the recommended installation torque.
The below mentioned recommendations are for spark plugs in new and unmodified condition. Typically the recommended installation torque is noted on the packaging.

Spark Plug M14 – Installation torque 30-40 Nm

Spark Plug M18 – Installation torque 50-60 Nm

Spark Plug 7/8″ – Installation torque 70-80 Nm

Please also always verify the engine manufacturer’s recommended installation torque. In case of deviations please contact the engine manufacturer.
Improper handling can lead to malfunction of the product. Federal-Mogul generally recommends application of a retaining device for the spark plug/boot assembly.
Federal-Mogul does not provide any expressed or implied warranty for a product which was altered by a party other than Federal-Mogul.
