Amazing quality

I’m redoing my entire cooling system and I was honestly fairly surprised with how quality these parts are and how well they fit. I will definitely be buying another one. I just wanted to buy one as a sample and let me tell you it looks amazing and works well. Highly recommend these to anyone doing a AN conversion for their car. I have an S13 with an SR20DET and these will also work with metric barbed radiators. Just make sure you measure prior to buying.

Thank you so much for taking the time to leave such a positive review! We are thrilled to hear that our -16AN Water-Neck Adapters exceeded your expectations and fit perfectly in your cooling system. We strive to provide high-quality products that are easy to use and we are glad that you found them to be just that.
