Are both plugs the same in each cylinder on the hemi?

In a HEMI engine, the spark plugs in each cylinder are generally the same type and specification, ensuring consistent performance across all cylinders. However, it's essential to follow the manufacturer's recommendations for spark plug specifications, including heat range and gap settings. While both plugs may be similar, some applications may have variations based on design or tuning requirements. Always consult the specific engine manual for guidance.
