Review on 🔌 NGK 2771 V-Power Spark Plug - UR5, 4 Pack: Optimal Performance for Your Engine by Matthew Carr

These are copper spark plugs. Newparts recommends using copper spark plugs instead of platinum. The 1997 Ford 7.5L engine must use platinum spark plugs in order to comply with state and California state emissions labels on the engine. Doesn't Newparts violate federal and state laws? We recommend contacting the California Air Resources Board to determine if new parts violate federal or California laws regarding the use of spark plugs that do not meet federal and California emission standards and are not recommended by Ford Motor Company , stating that they only use spark plugs listed on the Federal and State of California emissions labels affixed to the engine. PS copper spark plugs work on older engines that do not require platinum. According to Ford, copper connectors don't last as long as platinum.
