Installation Notes

Verify the vehicle’s required gap before installation and adjust only if needed; listed applications call for 0.050 in. on many Chrysler, Dodge, and Plymouth models, while the 2000 Chrysler Voyager notes 0.044 in. Use the specified flat-seat design and confirm the 14 mm thread diameter, 0.75 in. reach, and 5/8 in. hex match the engine specification. Always follow the vehicle service manual for torque and final gap verification.
