I was very skeptical of ordering from Autoplicity, as I've never heard of them. They had everything I needed in stock and shipped very quickly, and for a much better price than my normal suppliers at Jegs and Summit Racing. I would recommend them to everyone...............Jeff

Fast shipping cheapest I could find, easy to deal with, great product

Very good prices and good shipping prices. found my parts cheaper then any place else. Thanks to Autoplicity for filling my order #8498 of 4/02/12 quickly and accurately. I will be back.

The item has not been delivered yet. But the email updates are great. And I found this much cheaper than elsewere.
