Bosch Ignition Coil 098622A210 for GM vehicles - Direct-Fit Replacement, Corrosion-Resistant

Bosch Ignition Coil 098622A210 is a direct-fit replacement coil designed to restore strong, consistent spark energy and reliable engine starts for compatible GM vehicles.

When an ignition coil weakens, starting becomes harder, fuel burn can become inefficient, and drivability may suffer. Bosch designs this coil to meet or exceed original equipment specifications, delivering corrosion-resistant connectors, vibration and temperature resistance, and the voltage stability required for reliable ignition. Built with precise engineering and high-quality materials, the 098622A210 is intended for a long service life under demanding conditions.

How will this coil affect starting and everyday performance?

Replacing a worn coil with the Bosch 098622A210 returns consistent spark energy to the plug electrodes, which helps the engine start quickly and run smoothly across operating temperatures. You can expect improved cold-start responsiveness and steadier idle under normal conditions.

• Restores proper voltage delivery to spark plugs for reliable ignition
• Improves cold-start and low-speed drivability
• Reduces misfires and rough idling caused by weak coils

Is this coil a direct fit for my vehicle and which models are compatible?

The 098622A210 replaces OE numbers 12611424 and 8126114240 and was manufactured to match the original form, fit, and connector layout. It fits a range of GM vehicles across Buick, Cadillac, Chevrolet, GMC, Hummer, Isuzu, Pontiac, and Saab lineups, but fitment may vary by engine and trim.

• Common fits: Cadillac CTS and Escalade families, Chevrolet Silverado, Tahoe, Camaro, Corvette
• Includes many models of Buick LaCrosse, Rainier; GMC Sierra and Yukon series
• Always verify with your vehicle’s year/engine using the fit checker before purchase

What makes Bosch’s design durable under heat, vibration, and road use?

Bosch uses precision manufacturing and corrosion-resistant electrical contacts to ensure steady connectivity and resistance to harsh operating conditions. The coil assembly resists temperature-related degradation and mechanical vibration—common failure modes in ignition components—so it maintains performance over time.

• Corrosion-resistant connectors prevent electrical loss at the terminals
• Materials selected for high temperature tolerance and vibration damping
• Manufactured to meet or exceed OE performance and longevity targets

How simple is installation and what should I check when replacing a coil?

Installation is straightforward for anyone comfortable working under the hood; the Bosch coil uses the same mounting and connector layout as the original part. Before installing, inspect plug wires and spark plugs, and ensure connector pins are clean and fully seated to avoid ignition issues after replacement.

• Direct-fit design for original mounting points and plug orientation
• Check spark plug condition and gap; replace if worn
• Securely seat connectors and inspect surrounding wiring for damage

Who is this for: The Bosch 098622A210 is for owners and technicians who need a reliable, OE-quality ignition coil for compatible GM cars, trucks, and SUVs. It’s suited for drivers experiencing misfires, hard starts, rough idle, or those performing preventive maintenance on older coils. If you require long-term resistance to heat, vibration, and corrosion while maintaining factory-style performance, this Bosch coil is engineered to meet those needs.
