I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

vert simple.

very good price fast shipping

Found Autoplicity by doing Google search looking for Corsa Sport Axle Back exhaust for my 2008 GT500. By far the best price, even cheaper than other big companies with free shipping by far. Ordered them on Thursday afternoon and got them 24 hours later in NY with the standard shipping. Could'nt be happier.

fast, polite service when we had a question
