Key Details to Confirm Before Ordering

OE Number

Match the OE number 12666339 on the original coil label before sample review, quotation or a bulk order.

Engine Code

Check the engine code (LGW) and the production date. The same model name can use different engines and coils in different markets.

Connector and Mounting

Compare the connector shape, locking tab, boot length and mounting ear position with the original part. Similar coils can look alike in photos, so final matching should not rely on appearance alone.
