Refer to Vehicle Emission Control Information (VECI) decal for spark plug and gap specifications.
Spark Plug Part Number for a 3.8L EFI engine: AWSF-44C
Spark Plug Part Number for a 3.8L EFI S/C engine: AWSF-34PP (early built vehicles with the Supercharged engine had double platinum tip spark plugs which were identified with AWSF-34 PT. ASWF-34 PP is the correct replacement).
