I just want to let you know I am blown away by the quality of this thing. I have purchased a lot of radiators in my life, and this is probably the nicest one I have ever laid my hands on. The fact I was able to get something this solid for half the cost of a replacement plastic/aluminum unit is mind blowing, thanks again for everything and I hope to do business again in the future.

We are very pleased with how well your radiators are being received by our customer base. They really appreciate us offering more than the far east plastic and alloy replacements that are flooding North America's aftermarket scene.
