Great price and shipping is more than reasonable.

Received the spider gears a day late due to weather conditions. Overall great!

I was searching around for a K&N cold air intake for my Tahoe. After searching Autoplicity had the lowest price hands down. I ordered on a Wed. evening, and it was on my door step Friday afternoon with standard shipping. I couldn't of asked for better service. The price was $100 cheaper than everyone else. I will be using Autoplicity again.
