The 1982 EXP/LN7 vehicles built prior to September 4, 1981 were built with gasket type AGSP32 spark plugs. EXP/LN7 vehicles built after September
4, 1981 are equipped with taper seat, AWSF32 spark plugs which feature lower installation torque.
NOTE:
The gasket type AGSP32 plugs and the taper seat type AWSF32 plugs are not interchangeable. The AWSF32 plug has fewer threads and cannot be
used in the 1982 EXP/LN7 vehicles built prior to September 4, 1981.
When changing spark plugs in a 1982 EXP/LN7 vehicle, be sure to check the following:
1.
Engine Emission Decal: to verify the type of plug installed and proper gap.
2.
Plug type being removed to confirm that the replacement plugs are correct.
The chart may be used as a handy reference.
