BDFHYK UF413 ignition coil packs are OE-style aftermarket replacement parts for listed GM V8 service groups using a matching UF413-style coil design. Because many GM models can look similar online but use different coil styles, confirm the exact year, model, engine, connector shape, coil body, mounting points, and OE reference against the original ignition coil before ordering.
| Make | Models | Fitment Notes |
|---|---|---|
| Chevrolet | Silverado, Tahoe, Avalanche, Corvette, Camaro, Colorado, Caprice, Express, LCF, W4500 Tiltmaster | Listed GM V8 service groups; confirm exact engine and coil style. |
| GMC | Savana, Yukon XL, Canyon | Compare connector shape, coil body, and OE reference. |
| Cadillac | Escalade ESV, CTS | Confirm model year and engine before installation. |
| Other Listed Makes | Buick, Hummer, Isuzu, Pontiac, Saab, Workhorse | Confirm exact service group and original coil design. |
A weak ignition coil may contribute to hard starting, rough idle, hesitation, weak acceleration, reduced fuel economy, misfire symptoms, or a check engine light. Similar symptoms can also come from worn spark plugs, wiring problems, fuel delivery faults, intake leaks, sensors, or engine mechanical condition.
Install on a cool engine. Inspect the spark plugs, coil boots, wiring connectors, and mounting area before installation. BDFHYK ignition coils are OE-style aftermarket replacement parts, not factory-branded GM, Chevrolet, GMC, Cadillac, or related brand parts.
