This is Peter. With IRC Construction, we bought the product about four years ago, and I got a Tundra that was blowing out white smoke,out of the back,and the truck has now over 300,000 miles. It’s still going strong. They wanted $5000 at the time to fix the engine, and for us, I think I paid  couple of hundred, I don’t remember. It’s been a while how much we paid for the product. It has been excellent so far. So we’ve definitely got our money’s worth out of a great product. My friend has a head gasket problem now so I looked to see how to order some more. Great technical support. Thank you.
