A-Premium Ignition Coil Pack Set of 8 (Square Coil) — 3‑Pin Direct-Fit OE-Match for GM V8s

The A-Premium Set of 8 Ignition Coil Pack (Square Coil) is a direct-fit, 3-pin replacement ignition coil kit engineered for many GM V8 engines, delivering precise spark control for a reliable ignition system.

If your vehicle is equipped with one of the compatible Chevrolet, GMC, Cadillac or Buick V8 engines, these A-Premium coil packs are built to match OE mounting, connections and electrical specifications. Each coil is designed for a bolt-on valve-cover mounting, 12V operation and the terminal and resistance values needed for predictable ignition performance. The kit includes eight coils so you can replace an entire V8 ignition bank at once for consistent spark and simplified troubleshooting.

Which vehicles will these coils fit?

These A-Premium coils cover a broad selection of GM models across Chevrolet, GMC and Cadillac lines with specific V8 displacements and model years. Fitment targets engines like 5.3L, 6.0L, 6.2L and 6.6L used in trucks, SUVs and performance cars. Always cross-check OEM reference numbers and your vehicle’s year/engine code before ordering.

• Chevrolet Silverado 1500: 5.3L (various years) and 6.2L (2014–2019/2022)
• Tahoe/Suburban/Yukon/Yukon XL: 5.3L and 6.2L model years listed in product features
• Camaro and Corvette: compatible 6.2L V8 model years 2014–2021 (see full list)
• GMC Sierra, Cadillac CTS/Escalade, Express vans and other listed fits—including 6.6L on Express models

How do these coils match OEM specifications?

Each coil uses a 3-pin blade terminal and mounts with a bolt to the valve cover just like the original equipment. Electrical characteristics align with OEM ranges: primary resistance near 0.79 ohms and secondary resistance around 7.7 kΩ within tolerance. That compatibility helps preserve timing and ignition control behavior when replacing old or failing coils.

• Terminal type: 3-pin blade for direct connector compatibility
• Mount style: bolt-on valve cover attachment for OE alignment
• Voltage: standard 12V automotive electrical system
• Resistance: primary 0.79±10%, secondary 7.7±10%

What should I expect during installation and maintenance?

Installation is straightforward for anyone familiar with basic engine work: disconnect battery, remove ignition boot or wiring harness, unbolt the coil and swap in the replacement. Ensure connectors click fully and torque mounting bolts to manufacturer spec. After replacement, clear any stored codes and test drive; consistent operation across all eight coils reduces misfire risk and simplifies diagnostics.

• Tools needed: basic socket set, torque wrench, dielectric grease recommended
• Installation time: typically 30–90 minutes depending on engine access
• Post-install: clear error codes and inspect for steady idle and acceleration
• Maintenance: coils are sealed; inspect connectors and boots periodically

Who is this for? The A-Premium Set of 8 Ignition Coil Pack (Square Coil) is aimed at owners and mechanics working on GM V8 vehicles who want a full-bank replacement that mirrors OE fit and electrical specs. It’s ideal when multiple coils show wear or codes, when doing a performance refresh, or when preparing a vehicle for long-term reliability. Backed by a one-year unlimited-mileage guarantee, the kit suits professional shops and DIY enthusiasts who need a dependable, complete ignition coil solution for compatible Chevrolet, GMC and Cadillac engines.
