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*

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!

Very easy hope they are the right parts!

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.

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

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
