NPAUTO Round Ignition Coil Pack Set for GM V8 4.8/5.3/6.0 — 8-Pack Direct-Fit Replacement, OE-Style Connectors

NPAUTO round ignition coil pack set of eight replaces factory coils on many Chevy, GMC, Cadillac and related V8 4.8L/5.3L/6.0L engines from 1999–2007.

This complete eight-coil kit is designed as a direct-fit replacement for worn or failed ignition coils on a wide range of General Motors V8 trucks, SUVs and vans. Engineered to match OE mounting points and electrical connections, the set restores consistent spark delivery across all cylinders — helping to eliminate misfires, rough idle and hesitation caused by failing coils. The package lists multiple interchange numbers for easy cross-referencing and covers popular models such as the Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Express van and Hummer H2.

Which vehicles does this coil pack set fit?

How does swapping to these NPAUTO coils help engine performance?

Replacing degraded coils with a matched set restores even spark distribution, which stabilizes idle and improves throttle response. While not a performance upgrade in the sense of increasing horsepower beyond factory outputs, fresh coils reduce misfires and combustion inefficiencies that can rob drivability and economy.

• Reduces cylinder misfires and rough idle for smoother running
• Restores consistent spark timing and combustion efficiency
• Helps recover lost throttle response and acceleration

Are these coils easy to install and do they match original connectors?

The set is designed as a direct-replacement with OE-style electrical terminals and mounting dimensions, so installation is straightforward for anyone comfortable with basic engine work. Typical installation requires removing the engine cover (if present), unplugging the old coil, unbolting and swapping in the new coil, then reconnecting — repeat for each cylinder.

• Direct-fit electrical plugs and bolt locations for quick swap-out
• Sold as a full set of eight to replace every coil at once
• Works with factory ignition boots and spark plug configurations

What interchange numbers and part references should I check?

NPAUTO provides common interchange references so you can confirm fitment against your vehicle’s existing part numbers. Cross-referencing these helps ensure compatibility, especially when working from an older or aftermarket parts history.

• Common cross-refs: D585, C1251, UF262, UF-262
• Additional numbers: 19005218, 10457730, 12563293 and related OE codes
• Compare to the part on your engine or parts manual before purchase

Who this is for: Drivers and mechanics seeking a cost-effective, full-set replacement for failing ignition coils on GM V8 trucks, SUVs and vans from roughly 1999–2007. This kit suits owners who prefer to replace all coils at once to avoid recurring diagnostics and to restore smooth daily driving, as well as technicians looking for a direct-fit aftermarket option that matches factory connections and mounting. Always verify model year and engine displacement before ordering to confirm compatibility.
