This Buick / Cadillac / Chevrolet / GMC ignition coil is supplied for the listed OE numbers 12654078 and 099700218. It features a 4 pins connector and with-module configuration, so connector layout, module structure, housing design, and mounting details are useful points to review when selecting a replacement product.
During product comparison, buyers can check the listed OE number together with connector orientation, terminal layout, plug direction, housing profile, mounting position, and overall dimensions of the original coil. Reviewing several matching details together provides a clearer reference than judging the product by exterior appearance alone.
Connector and Module Details to Check
Listed OE Numbers
Check the applicable listed OE number against the original part during quotation, sample review, catalog preparation, or order confirmation. The OE reference can be considered together with the physical structure of the coil.
4 Pins Connector
The 4 pins connector is an important visible matching feature. Connector shape, terminal arrangement, locking position, plug direction, and installation orientation can be compared with the original ignition coil.
With Module Configuration
This ignition coil is listed as with module. Module configuration can be reviewed together with connector and housing details when confirming the required replacement structure.
Electrical Construction and Inspection Focus
Ignition coil operation is related to the condition of the primary and secondary windings, internal insulation, terminals, electrical connections, and control-related components within the coil assembly. During product evaluation, these areas can be considered together with connector fit, housing condition, and installation dimensions.
Engine heat, temperature changes, vibration, and repeated electrical loading are common operating conditions around ignition components. Depending on the buyer's inspection requirements, evaluation may include connector and terminal condition, housing and assembly condition, insulation-related characteristics, and relevant electrical measurements.
Sample and Batch Order Reference
During sample evaluation, the replacement coil can be compared with the original part for the listed OE number, 4 pins connector, with-module structure, connector orientation, housing profile, and mounting details. Original coil photos or connector close-ups can also be used as additional reference when further comparison is required.
For regular purchasing, the confirmed sample can serve as a reference for subsequent order communication. Product version, packaging method, label information, required quantity, and other project-specific details can be reviewed according to the buyer's purchasing requirements.
