HQPASFY UF262 Ignition Coil Kit with Iridium Plugs & Wires — Round Delphi Coils, 8-Cylinder Tune-Up

Complete tune-up kit with eight HQPASFY UF262 round ignition coils, iridium spark plugs, and high-performance spark plug wires designed to replace worn ignition components on compatible Chevy, GMC, Cadillac, Hummer and Isuzu V8 engines.

If your V8 truck or SUV is running rough, misfiring, or showing reduced responsiveness, this all-in-one ignition kit restores consistent spark delivery across all eight cylinders. The set is engineered for direct fitment on vehicles equipped with Delphi-style round ignition coils; it does not fit engines that use square Mitsubishi-style coils. Included components are matched to deliver reliable electrical performance and easier installation compared with sourcing parts separately.

Which vehicles and engines will this kit fit?

This HQPASFY UF262 kit covers a wide range of GM platforms from the late 1990s through the 2000s. It supports many Avalanche, Silverado, Sierra, Suburban, Tahoe, Yukon, Express/Savana, Escalade, H2, Envoy/Ascender and related models when equipped with compatible V8 engines listed in the fitment notes. Always verify your vehicle uses round Delphi-style coils and cross-check part numbers before ordering.

• Fits 4.3L, 4.8L, 5.3L, 5.7L, 6.0L, 6.8L and 8.1L V8 variants on specified model years.
• Compatible with many Chevy, GMC, Cadillac, Hummer and Isuzu models (see product fitment).
• Replaces UF262, 10457730, D585, 12563293 and similar round coil part numbers.

How do these coils, plugs and wires improve daily driving?

Replacing aged coils, worn iridium plugs, and brittle wires helps restore crisp throttle response, smoother idle and steadier acceleration. The kit’s matched components reduce electrical losses and help minimize misfires that can affect drivability and fuel efficiency. Installation returns the ignition system to near-original performance without complicated upgrades.

• Iridium plugs retain a stable spark gap longer than conventional plugs.
• Round Delphi-style coils deliver focused high-voltage output to each cylinder.
• Durable wires resist heat and abrasion in the engine compartment.

What should I check before buying this ignition kit?

Confirm your vehicle’s engine family and coil style—this kit fits round Delphi coils only and will not match square Mitsubishi coils. Cross-reference the UF262 and OEM numbers listed in the product details with your current parts. Also check connector types and spark plug thread sizing to ensure a direct replacement without modifications.

• Verify coil shape: round Delphi-style (not square Mitsubishi-style).
• Compare existing part numbers to UF262, 10457730, D585 and listed equivalents.
• Check engine displacement and model year against the compatibility list.

What can I expect from quality and warranty coverage?

HQPASFY supplies this set with materials chosen for thermal and vibration resistance common in engine bays. Each component undergoes quality control to help ensure consistent ignition performance under normal driving conditions. The product includes a 12-month warranty for manufacturing defects and workmanship concerns.

• Designed for engine bay temperatures and repeated ignition cycles.
• Manufacturing checks intended to maintain consistent spark performance.
• 12-month warranty covering defects and fitment issues (terms apply).

Who is this for: This HQPASFY ignition kit is aimed at DIY mechanics and professional technicians who maintain late-1990s through mid-2000s GM V8 trucks and SUVs that use round Delphi-style coils. It’s a practical choice for owners wanting a single, matched replacement package — coils, iridium plugs, and wires — to restore dependable ignition across all eight cylinders without sourcing individual parts.
