Frequently asked questions
Is the car model alone enough to make the selection?
Not always. There can be different part versions within a single model, so it's worth comparing the year, engine, markings, and photos.
Where to check the OE/OEM number?
It's most often found on the removed part, label, or housing. If this listing lists numbers, compare them to your component.
What to do if a part looks different?
Don't order based solely on a similar name. Compare the mounting, connectors, shape, and markings, and if in doubt, verify compatibility before purchasing.
