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.
