These guys were real helpful when I was looking for an EGR valve. Great communications and fast delivery, the valve did exactly as It was meant to do and it was a lot cheaper than everywhere else I looked. I'll be using eAuto Parts again. Top banana.

The correct part was rapidly identified and located, and was despatched promply to my chosen repairer in time for the work to be done on schedule. Very pleased with the service and will be using eAuto Parts again.
