This Opel ignition coil is developed for the listed OE number 1208121. It is a 4 pins ignition coil with module, supplied according to the Opel product information shown on this page.
For this coil type, confirmation should focus on the OE number, 4 pins connector, with-module structure, housing shape, and original coil appearance together. This helps reduce mismatch when similar ignition coils have close plug positions, similar mounting angles, or similar catalog descriptions.
Product Matching and Structure Details
OE Number Check
Confirm 1208121 before quotation, sample review, catalog listing, or batch order preparation. OE number checking should come before judging only by product image, general Opel wording, or similar coil body shape.
4 Pins Connector
The 4 pins connector is a key identification point for this ignition coil. Connector shape, pin layout, locking position, plug direction, and installation angle should be compared with the original coil before final confirmation.
With Module Structure
This ignition coil is supplied with module. The module status should be confirmed together with connector and housing details to avoid mismatch during parts matching, warehouse stocking, or repeat procurement.
Performance and Quality Focus
A correctly matched ignition coil helps provide stable high-voltage spark output for combustion, supporting smoother starting, steadier idle, and more consistent engine response after installation.
For aftermarket supply, quality checking should focus on winding consistency, insulation performance, terminal contact, connector fit, heat resistance, and housing durability. These details help the coil work more reliably under vibration, temperature change, and repeated engine operation.
Quotation and Supply Preparation
This coil can be included in ignition system checking when misfire, rough idle, hard starting, weak acceleration, unstable running, or check engine warning appears. It should be reviewed together with spark plugs, wiring condition, connector contact, and related control signals.
To speed up quotation or sample confirmation, prepare the listed OE number, 4 pins connector, with-module structure, order quantity, packaging request, label content, and expected delivery time. Original coil photos, connector close-ups, and label-area images can make visible-detail comparison clearer before arranging regular supply.
