I thought my order was going to take longer to ship and it surprised me after I called Autoplicity I thought another few days before it shipped and it arrived. The lowest price I found on my Mishimoto radiator was on Autoplicity.

Quality air cleaners. They also come with a custom wing nut. Edelbrock comes with a cheap cast wing nut.

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.

I was amazed to find the air intake I wanted at the price offered by Autoplicity. No one else came close and the item was shipped very quickly. This store has been added to my favorites list........Thank You!!!!

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.

I received my Corsa exhaust for my Sequoia today; I had issues with Autoplicity with regard to the order/availability which once brought to their attention was rectified; in the end I had to wait a little longer than expected to receive my order but it was resolved and hopefully the management learned something from this experience.
