I was looking for a rebuild bottle for my hot rod and settled on the Jaz Trap. I liked the black, it won't stand out like the other colors. I also know the Jaz brand and thought it was a quality product. There were no instructions included, which wasn't a problem for me. But someone unfamiliar with how the heat exchanger works can install it incorrectly. The kit also didn't come with a hose, which meant I had to go to my local parts store to pick it up before I could complete the installation. It works well, I'm happy with the trap itself, but the instructions and hose would have made it so much better.
