The kit centers on the UF262 round-style coil (confirm coil shape first), paired with fine-wire iridium spark plugs and high-temp insulated plug wires. Materials and construction target corrosion resistance, vibration tolerance and stable conductivity so ignition performance stays steady mile after mile.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles does this UF262 round coil and plug set fit?\u003c\/h3\u003e\n\u003cp\u003eThis kit fits a specific range of GM trucks and SUVs from 1999 to 2006 that use the UF262 round ignition coil.
