Ignition Coil 26163171/55571790

This Buick ignition coil is supplied for the listed OE numbers 26163171 and 55571790. It uses a 7 pins connector and with-module configuration, so connector layout, terminal arrangement, housing profile, mounting structure, and overall coil design are useful points to review when confirming a replacement product.

Buyers can compare the listed OE numbers with the connector orientation, terminal position, plug direction, housing shape, mounting points, and dimensions of the original coil. Reviewing these details together provides a practical basis for product matching rather than relying only on the exterior appearance of the ignition coil.

Product Matching Details to Verify

Listed OE Numbers

Confirm 26163171 or 55571790 against the original component during sample review, quotation, catalog preparation, or order confirmation. The listed OE references can be checked together with the connector configuration, housing structure, and mounting arrangement of the original ignition coil.

7 Pins Connector

The 7 pins connector is an important physical matching point for this coil. Connector shape, terminal layout, locking position, plug direction, and installation orientation can be compared with the original component before confirming the replacement.

With Module Structure

This ignition coil is listed as with module. The module configuration should be reviewed together with the connector, housing design, mounting arrangement, and other structural details when checking the required replacement configuration.

Winding, Insulation and Electrical Condition

Ignition coil operation involves the primary and secondary windings, magnetic components, internal insulation, terminals, and electrical connections. These areas work together during voltage transformation and form important points when reviewing the electrical and structural condition of a replacement coil.

Engine heat, vibration, repeated temperature changes, and electrical loading are common operating conditions for ignition components. Product evaluation can therefore include terminal contact, connector condition, housing integrity, insulation-related condition, and relevant electrical measurements according to the applicable product or vehicle requirements.

Sample and Batch Consistency Review

During sample evaluation, the replacement coil can be compared with the original part using the listed 26163171 and 55571790 OE references, together with the 7 pins connector, with-module structure, connector orientation, housing profile, mounting details, and overall dimensions.

For repeat or batch purchasing, an approved sample can serve as a reference for connector configuration, product dimensions, housing appearance, visible assembly details, labeling, and packaging requirements. Additional specifications can be confirmed according to the actual purchasing and supply requirements.
