Googled part I needed, autoplicity was cheapest, and got two for the price others wanted one for. Good deal. When delivered, the item didn't fit. Emailed support, refunded my money, no hassel.

Fast Check Out :) I like that

Good

I ordered a Jet Powr-Flo, SKU: JET-69190, from Autoplicity and it was at least 40% off the regular JET price. The site was off on all the vehicles the component fits, but I knew what part to get and I'm completely satisfied. My 2008 Mustang is running smoother than ever and wasting less fuel. So for any performance parts I'll search the maker sites first but I'll purchase from Autoplicity first.

better price than anyone on eBay, and in stock and shipped immediately, paid one day had it the third day
