NPAUTO Ignition Coil Pack for GM V8 4.8/5.3/6.0/6.2L – Set of 8, OE-Fit High Voltage Replacement

Premium replacement set of eight round ignition coils engineered to restore reliable spark delivery for V8 4.8L, 5.3L, 6.0L, and 6.2L GM engines from 2006–2017.

If your V8-powered Chevrolet, GMC, or Cadillac is showing misfires, rough idle, or loss of power, worn or failed ignition coils are often the root cause. This NPAUTO eight-coil pack replaces the OE coil packs used across a wide range of GM trucks, SUVs, and performance models, offering consistent voltage output and fitment that matches factory specifications. The set covers many popular models including Silverado, Sierra, Tahoe, Yukon, Escalade, and select Buick, Pontiac, Saab, Hummer, and Isuzu applications.

How will these coils improve engine performance?

New coils restore the ignition system’s ability to deliver a strong, stable spark to each cylinder. That reduces misfires and helps the engine run smoother under load and at idle. Proper spark timing and intensity are essential for combustion efficiency and throttle response.

• Delivers consistent high-voltage output for reliable combustion
• Reduces cylinder misfires and rough idle events
• Improves throttle response and steadies RPM under load

Are these coils compatible with my specific vehicle?

This NPAUTO set is designed as a direct-fit replacement for many GM V8 engines from 2006–2017. Compatibility includes multiple Chevrolet, GMC, and Cadillac platforms along with various Buick, Pontiac, Saab, Hummer, and Isuzu models when equipped with the listed engines. Always confirm part interchange numbers or compare against your OEM coil to ensure exact match.

• Fits 4.8L, 5.3L, 6.0L, 6.2L V8 engine families (2006–2017)
• Interchange numbers: UF-414, UF414, 12573190, 610-00159, 8125731900, 12578224, 5C1555, 12699382
• Common models covered: Silverado, Sierra, Tahoe, Yukon, Escalade, Suburban, Camaro, Corvette, Impala

How difficult is installation and what should I prepare?

Installation is typically straightforward and follows the factory coil replacement procedure. Basic hand tools and a torque wrench are usually all that’s required, and the coils install in the same orientation as the originals. If you’ve changed spark plugs recently, replacing coils at the same time is a smart preventive step.

• Requires basic tools: ratchet, sockets, and torque wrench
• Recommended to inspect or replace spark plugs when changing coils
• Follow OEM torque specs and connector seating for a secure fit

What reliability and quality features does this NPAUTO pack offer?

These aftermarket coils are built to meet performance and durability expectations for modern GM V8 engines. Materials and internal windings are optimized for heat resistance and sustained electrical output. While aftermarket, they are manufactured to fit tight OE tolerances and to integrate with factory wiring and ignition modules.

• Engineered for heat resistance and stable coil windings
• Designed to meet factory fitment tolerances and electrical specs
• Sold as a full eight-coil kit for complete cylinder coverage

Who is this for: Drivers and technicians who need a direct-fit, full-replacement ignition coil solution for GM V8 engines—owners of Silverados, Sierras, Tahoes, Yukons, Escalades, and other compatible models looking to eliminate misfires, restore smooth idle, and regain responsive performance. Ideal for DIYers replacing all coils at once or shops performing scheduled ignition system maintenance.
