First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

They were Very quick and i was very happy with the service i got!! 9-10*

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

Quick n easy

The ordering process was very simple and the prices could not be beat. The processing time to ship the order was a little longer than usual, but for the price savings, it was well worth it!

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.

Great customer service, item shipped quickly. Very satisfied.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.
