I wish mine would have worked, and Magnuson wouldn't have botched the tensioner issue for the better part of a year.
Just don't get a defective tensioner, and you'll be happy.
The coolant lines and tank are very cheaply done. Like others, mine was leaking after only a few months. Had I kept the SC, I would have re-done the tank and lines. You could get away with just better clamps, but the tank is really thin. It's not something that feels at home on such a well-built kit.
Not the greatest experience for me and Magnuson's customer service left a bad taste in my mouth. But I'm the exception, not the norm.
