These ENA coils are the round UF262 style (not the square UF271), sold as a complete set of eight with a plug-and-play design and a 12-month warranty. They match OEM electrical specs and mounting style for many 4.8L, 5.3L and 6.0L engines from late 1990s through mid-2000s models.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I confirm these are the right coils for my truck?\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, visually compare your existing coil housing to ensure it’s the round UF262 style rather than the square UF271.
