NPAUTO Ignition Coil Pack Set for GM V8 4.8/5.3/6.0/6.2 — 8-Piece OE-Fit Replacement, Direct Swap

If your Chevy, GMC or Cadillac exhibits misfires, rough idle, or reduced performance, worn ignition coils are a common cause. This NPAUTO coil pack set provides eight direct-replacement coils that match OE fitment and electrical characteristics for many GM V8 applications, giving you a straightforward way to restore spark delivery and driveability without modifying your engine.

How will these coils improve my truck's performance?

Replacing faulty coils restores strong, consistent spark to each cylinder, which helps the engine run smoothly and efficiently. While results depend on your engine condition and other ignition components, fresh coils remove one common source of misfires and power loss.

• Restores consistent spark timing across cylinders
• Reduces misfires and uneven idling when coils were failing
• Works with factory ignition harness and plug types for plug-and-play replacement

Which vehicles and engines are these coils compatible with?

This set is intended for GM V8 engines including 4.8L, 5.3L, 6.0L and 6.2L models from mid-2000s through 2017. It's widely compatible across full-size GM trucks, SUVs and performance cars when the original part numbers or engine family match.

• Fits many Chevy models: Silverado, Tahoe, Suburban, Avalanche, Camaro, Corvette and more
• Compatible with GMC trucks/SUVs like Sierra and Yukon, plus vans and HD variants
• Also fits Cadillac Escalade/CTS and several Buick, Pontiac and Saab models noted for these V8s

What parts and numbers does this set replace?

These coils interchange with common OEM and aftermarket references so you can confirm fitment before purchase. Cross-reference the listed part numbers with your vehicle's VIN or service manual to ensure compatibility.

• Interchange references include UF-414, UF414 and OEM-style numbers like 12573190 and 12578224
• Sold as a complete set of eight coils to replace every cylinder on V8 engines
• Designed to match factory connector, terminal and boot dimensions for direct swap

How difficult is installation and what should I check during replacement?

Installation is typically straightforward for DIYers with basic hand tools: remove the engine cover, unplug the coil connectors, unbolt and swap each coil, then re-torque fasteners. While replacing, inspect spark plugs, wiring and rubber boots for wear to avoid repeat failures.

• Requires basic tools and about 30–90 minutes depending on engine accessibility
• Inspect spark plugs and ignition harness for damage during installation
• Follow torque specs and ensure connectors clip fully to prevent electrical issues

Who is this product for? This NPAUTO round ignition coil pack is aimed at owners and mechanics of GM V8 vehicles (4.8L–6.2L) from roughly 2006–2017 who need a full eight-coil replacement. It's appropriate for drivers troubleshooting misfire codes, restoring drivability after coil failure, or performing preventative maintenance on trucks, SUVs, vans and performance cars that use these coil designs.
