OE Numbers: The Most Reliable Way to Find the Right Part

In the European auto parts trade, the OE number is the most reliable basis for product matching. The GROPA online catalogue supports precise search by OE number, alongside product-name and vehicle-fitment searches. Note that a single part may correspond to several OE numbers — different model years and configurations may use different numbers. In the GROPA catalogue, all OE numbers of a product are listed in full for easy cross-checking. If you cannot find a number, contact us and we will be glad to help confirm it.
