great deal

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Lowest price on EBC brakes for my Subaru. Good speed on processing.

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.
