NB 1.8L Miata Radiator
I purchased this radiator because the stock one started leaking from the top at 135k miles and put it in myself no problem. I would definitely recommend this radiator if you plan on keeping your motor stock. The radiator works and I can drive my car again but the real story of getting the part is with the best of 1A Auto. I actually got this part three times. The first one came with a big hole in the box and the radiator was damaged, I talked to customer service and they shipped one out free of charge the same day. The second one arrives with a similar size hole in the box again, I talked to customer service, and once again they sent me another one free of charge. I learned that it was at fault of the delivery company - not 1A Auto. I am grateful for their customer service and support because I'm sure anywhere else I would have had to send the radiator back making the process much longer. I would definitely recommend purchasing one from 1A Auto!
