GM GENUINE PARTS Ignition Coil 12723610 — OE-Quality Replacement with Pure Copper Windings

The GM Genuine Parts 12723610 ignition coil is an OE-quality replacement that restores proper spark delivery using pure copper windings and corrosion-resistant laminations for reliable engine starts.

Designed and validated by GM engineers, this ignition coil matches the original equipment specifications for compatible Chevrolet, Buick, GMC, and Cadillac models. It boosts secondary system voltage to help ignite the air/fuel mixture during startup and maintains consistent spark under running conditions. Built-to-spec laminations and protective coatings reduce internal shorts and corrosion, giving you a durable replacement part that integrates with the vehicle's charging and ignition systems.

How does this ignition coil improve engine starting and performance?

The 12723610 coil raises the ignition system's secondary voltage so spark plugs receive a strong, stable spark for reliable combustion. That improved voltage stability helps reduce misfires and supports smoother idle and throttle response when the rest of the ignition and fuel systems are functioning normally.

• Pure copper windings for higher conductivity and durability
• OEM-matching lamination count and shape for correct output characteristics
• Protective coatings to limit dielectric breakdown and internal shorts

What design details ensure long-term durability?

GM Genuine Parts coils use coated silicone steel plates and often include molded plastic protection to keep external contaminants away from sensitive internal components. The plates are treated to resist corrosion, and the coil windings are insulated to withstand thermal cycling and vibration in the engine bay.

• Coated laminations to hinder rust and preserve magnetic properties
• Molded plastic shields to prevent exposure to moisture and debris
• Insulated windings to reduce risk of internal shorts and breakdown

Will this part fit my GM vehicle and meet factory standards?

Yes — GM Genuine Parts are either the original parts used in production or parts validated by General Motors engineers to the same specifications. The 12723610 ignition coil is manufactured to the size, lamination count, and electrical characteristics required to match OE performance for listed GM applications.

• Engineered and tested to GM validation procedures
• Form, fit, and function designed for compatible GM models
• May appear under previous ACDelco GM Original Equipment listings

How easy is installation and what should I check when replacing it?

Installation follows standard ignition-coil replacement steps: disconnect battery, remove electrical connector, unbolt the coil, and swap with the new unit. Check associated spark plug condition, wiring harness integrity, and mounting hardware to ensure optimal performance after replacement.

• Simple bolt-on replacement for compatible models
• Inspect spark plugs and connectors while replacing coil
• Use manufacturer torque specs and electrical reconnection procedures

Who is this for? The GM Genuine Parts 12723610 ignition coil is aimed at DIY enthusiasts, independent mechanics, and service shops seeking an OE-equivalent replacement for GM vehicles. If you're restoring reliable spark delivery, correcting misfires, or following scheduled maintenance with factory-approved parts, this coil provides the engineered fit, corrosion-resistant design, and validated performance expected for Chevrolet, Buick, GMC, and Cadillac applications.
