Hello -

Please ensure with any future posts you are more specific on your vehicle model. I have attached what we view. Also, please ensure you provide the engine size by Liter and the 8th digit of our VIN.

Not sure where you have your maintenance performed but many places don't use refur4bished parts. I have attached a ruff quote. Please remember that this is only a estimate as your area may be more or less depending on many factors.

Also you can purchase this part at say, Auto Zone or O'Reilly's for about $250 and do the work yourself and save quite a bit.

Hope this helps.

Thanks

One other thing.....you may have several recalls for your vehicle. These are normally paid for by the dealer. Please make sure you contact the dealer service department to see if any of these apply to your vehicle, especially the safety one.

Thanks
