CNPAPC UF262 Round Ignition Coil Kit 8pc — Fits 1999–2006 GM V8, Iridium Plugs & Wires

CNPAPC’s 8-piece UF262 round ignition coil pack with 41-962 iridium spark plugs and full wire set is a direct-fit ignition replacement kit for many 1999–2006 GM V8 models that restores reliable spark and smoother running.

If your Silverado, Sierra or Escalade is showing misfires, rough idle or poor throttle response, this matched coil, plug and wire kit is built to return consistent spark delivery and extend service life. 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.

Which vehicles does this UF262 round coil and plug set fit?

This kit fits a specific range of GM trucks and SUVs from 1999 to 2006 that use the UF262 round ignition coil. It does not fit applications requiring the UF271 square coil—verify the coil shape or VIN before ordering.

• 1999–2006 Chevrolet Silverado 1500: 4.8L & 5.3L
• 2003–2005 Silverado 1500: 6.0L; 1999–2004 Silverado 2500/2500HD: 5.3L & 6.0L
• 1999–2006 GMC Sierra 1500 and 2002–2006 Cadillac Escalade V8s listed in fitment

How are the coils, plugs and wires engineered for durability?

Each coil uses German-imported copper windings, high-temperature epoxy potting and silicone insulation to resist heat, moisture and vibration. The spark plugs feature a fine-wire iridium electrode for longer life and improved ignitability, while the wires are built to maintain low resistance under load.

• Coil composition: copper wire, epoxy, silicone insulation
• Plugs: iridium tip for extended service life (approx. 90,000+ km under normal conditions)
• Wires: reinforced insulation for stable conductivity and reduced crossfire

Will replacing these parts fix misfires and poor acceleration?

Replacing worn coils, fouled plugs and brittle wires commonly resolves ignition-related misfires and uneven throttle response. While this kit addresses most spark-system causes, always diagnose for secondary issues such as fuel, sensors or mechanical engine faults first.

• Addresses spark loss from degraded coils or wires
• Improves combustion stability with fresh iridium plugs
• Recommended to pair with diagnostic check for non-ignition causes

What OEM numbers and fitment checks should I confirm before buying?

The listing includes several OEM and cross-reference numbers to help verify compatibility; use photos of your original coil or provide your VIN to confirm exact fit. The UF262 round coil is often mistaken for UF271 square coils—matching the physical shape is crucial.

• Check labels: UF262, C1251 and many cross-reference numbers included
• Confirm coil shape (round vs square) against your existing unit
• When in doubt, send pictures or VIN to verify fitment

Who is this for: This CNPAPC kit suits owners and mechanics replacing the entire ignition pack on late‑90s to mid‑2000s GM V8 trucks and SUVs that require the UF262 round coil. It’s ideal when you want a matched set—coils, iridium plugs and wires—designed to work together for reliable spark delivery and extended service life. If your vehicle uses a square UF271 coil, select the correct part instead.
