I don't appreciate the added offers to "save" money by spending it on things I had no interest in when I bought the car part from you. Would have given 5 stars, but not after being harassed by subsequent ads.

It will depend on whether the shipping is as represented in our phone conversation.

Excellent service and fast shipping. A seller I would do business with again.

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!

Excellent

Great price and quick shipping!

Lowest price on the Internet, good packaging and fast shipping.

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
