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.
B
Best price I could find on the web even after paying for shipping!  Shipped in a couple of days and great service!
P
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.
M
Great customer service, item shipped quickly. Very satisfied.
