Cheap

This is my second time ordering from Autoplicity and both times they had the lowest price on the items I was looking for (brake pads and CAI filter). Fast shipping, my filter was at my door two days later. Overall very satified.

The only thing I would like to know is what the manifold kit comes with for hardware. Its not specified if they come with any hardware or gaskets at all and i would like to be prepared to do the job when they arrive in the mail.

Real easy to use

quick and easy! had no problems at all

lots of inventory, i ordered a hard to find air filter which was cheaper than all the other sites and shipped out fast. Nice!

I received excellent customer service from Autoplicity. I emailed them a question about my order and received an answer within an hour or so. I was very happy with this company

Great interface for figuring out if product fits my vehicle.

I ordered the Keep Toolbox Jerry can, what a great piece. Construction is pretty good for not being made in the US but it is rather heavy compared to real Jerry cans. Definitely a great piece!<br>-J Tuttle

Only place that stocked the full floor mats that I wanted for my Cruze - AND, best price. Quick shipping too. A+

Super group to deal with! Great prices, fast shipping and excellent communication! Who could ask for more! <br><br>Thank you,<br>Jody C.

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

Found part quickly. Price was competitive.

Website was easy and great to use. Received products and they were exactly what I was looking for! This saved me so much money doing the install myself and better parts than any auto shop out there. Thanks!
