All I can attest to is that after warm up, if I stopped for gas, or something, and shut off the car, it would be a very slow roll when I again turned the key. If I didn't catch it in the first couple of turns I was skrewd. This is before and after new cables(1/0) and new red top battery(in the trunk) install. Old stock starter/sol w/heatshield. Installed a used mini and haven't had a prob since(about six months now). Worked for me. Cost about:$150. Being able to start the car whenever I want to: Priceless. My.02
