HQPASFY UF262 Ignition Coil Kit with Iridium Spark Plugs & Wires — Set of 8 for GM V8 (Round Delphi, 1999–2007)

Complete ignition kit with eight HQPASFY UF262 round-style coils, iridium spark plugs and plug wires engineered to fit a wide range of 4.3L–8.1L GM V8 engines.

This all-in-one ignition bundle is built to replace worn coils, plugs and leads on many Chevrolet, GMC, Cadillac, Hummer and Isuzu models from the late 1990s through the 2000s. The kit is designed for vehicles that use the round Delphi-style coil (not compatible with square Mitsubishi-style coils). Each coil is produced to meet OEM fitment dimensions, while the iridium plugs and high-quality ignition wires are selected to ensure consistent spark delivery across all eight cylinders.

Which vehicles will this UF262 ignition set fit?

This set fits a broad lineup of GM trucks and SUVs equipped with V8 engines during the 1999–2007 model years. It covers many Avalanche, Express, Silverado, Sierra, Suburban, Tahoe, Yukon, Escalade, Savana, H2 and related models—refer to your vehicle’s coil style and part numbers before ordering.

• Designed for vehicles listed with round Delphi-style coils; not for square Mitsubishi-style coils.
• Common compatible engines: 4.3L, 4.8L, 5.3L, 5.7L, 6.0L, 6.8L, 8.1L V8 variations.
• Replaces OEM part numbers including UF262, 10457730, 12563293 and others—verify your part number first.

How does this kit improve ignition reliability during daily driving?

Worn coils, degraded spark plugs or brittle wires can cause misfires, rough idle or reduced throttle response. Replacing all three components at once restores a balanced ignition system and helps maintain even cylinder firing under load.

• New UF262 coils deliver consistent secondary voltage for reliable sparking.
• Iridium plugs provide a durable electrode for longer service life and steady ignition.
• Quality plug wires maintain low-resistance pathways to minimize energy loss and interference.

What should I check before buying to ensure fitment?

Confirming fitment avoids returns: check your vehicle’s model year and engine size against the fitment list and verify the coil physical style and OEM part number. This set is tailored for round Delphi-style coils—vehicles with square Mitsubishi-style coils require a different kit.

• Match your OEM coil part number (e.g., UF262, 10457730, 12563293).
• Inspect coil shape on your engine (round Delphi-style required).
• Cross-check model year and engine displacement from the compatibility table.

Can I install the set as a DIY job or should a technician do it?

The replacement process is straightforward for people experienced with basic engine maintenance: coil removal, plug replacement and routing wires correctly. If you’re unsure about torque specs, ignition timing or electrical connectors, having a professional complete the installation ensures proper operation.

• Simple hand tools and a torque wrench cover most installation steps.
• Follow OEM torque specifications for spark plugs and secure coil connectors firmly.
• Professional installation recommended if unfamiliar with ignition systems.

Who is this for: This HQPASFY UF262 ignition coil, iridium plug and wire set is intended for owners and mechanics servicing GM V8 trucks and SUVs from roughly 1999 to 2007 who need a full ignition refresh. It’s appropriate for those seeking OEM-style fitment, a cohesive replacement package for all eight cylinders, and a solution that simplifies parts matching when coils, plugs and wires are aged or causing drivability issues.
