This is my second time ordering from Autoplicity and both times they had the lowest price on the items I was looking for (brake pads and CAI filter). Fast shipping, my filter was at my door two days later. Overall very satified.

Easy

Lowest prices I found on the net and great customer service! Fast shipping too!

I ordered a universal Hurst Pistol Grip "shift knob" for my '12 Mustang GT. It squeezed to a perfect fit right where I need to grip it. It improved shift time and accuracy greatly and feels and looks great! Autoplicity had the best price on the web and I got this in 3 business days. I recommend this product.

Fast service and great prices. knowledgable sales persons, Hugh in stock items. Packing was excellent, doubled boxed.

Order was fast, had the products I wanted in stock, and vehry pleased. Thank you 5 star service.
