SPARK PLUG TORQUE RECOMMENDATIONS

How to Tighten Spark Plugs

Use the Champion torque recommendation below as a guide for tightening all spark plugs.

Step-by-Step Instructions

Tapered Seat Plugs

Step One

Install the new plug finger tight, and complete the installation with a torque wrench.

Note: If using a torque wrench vs. plug wrench, please refer to the Torque Recommendations chart below.

 

Step Two

Turn Finger Tight. A tapered seat plug does not use gaskets and requires one-sixteenth (1/16) turn.

Note: If using a torque wrench, please refer to the Torque Recommendations chart below.

Gasket Type Plugs

Step One

Turn Finger Tight. A new or reinstalled plug with a new gasket will require ⅜-⅝ turn to effect a gas tight seal depending on head material.

Note: If using a torque wrench, please refer to the Torque Recommendations chart below.

 

Step Two

For reinstalled plugs with a used gasket only a ¼ turn is required for gas tight seal for both cast iron and aluminum cylinder heads.

Note: If using a torque wrench, please refer to the Torque Recommendations chart below.
