Buick 1.0T Turbo Ignition Coil 12673523 1208121 UF836 Direct Replacement

If your Buick 1.0T turbo engine exhibits acceleration hesitation, rough idle, higher fuel consumption, or check engine light, it is usually due to aging ignition coil resulting in insufficient spark energy to ignite the mixture. This part converts low voltage to high voltage to accurately fire the spark plug and ensure smooth engine operation and power delivery. Fits Buick Excelle/Verano and other models with 1.0T turbo engines; OEM numbers 12673523, 1208121, UF836. During installation, disconnect the battery negative, replace with the original sequence, and inspect spark plug condition; simultaneous replacement is recommended to ensure ignition system compatibility.
