Easy peasy lemon squeezie

Quick and easy, shipping was expensive

I was very happy with Autoplicity and my order of the MMRAD-MIA-90X Mishimoto radiator for my Miata. I am in the process of building a Spec-Miata for racing and trying to keep the costs down. I found Autoplicity to have the best prices on the net. I received the rad real quick. There was a problem with the radiator but the guys at Autoplicity were easy to work with and I am expecting the new radiator in a week or so.
