If you have a turbocharger – whether it's factory, added or upgraded – the Turbo Timer should be included in your budget under the category: "peace of mind." The Turbo Timer allows you to leave your vehicle while the timer leaves your engine running anywhere from 10 seconds to 9.99 minutes. The gradual cool-down prevents bearing damage that can occur when a turbocharged engine is shutdown abruptly after normal driving. ("Spirited" driving and its more extreme temperatures would be even worse.) -> Black OR Silver finish, choose below
