| For those of you that live in the colder parts of the country and you leave your z outside or in an unheated garage, you can install one of these block heaters and keep your engine warm all winter long. This unit replaces one of your engine block soft plugs and has a cord on it that you run up to your grille. Then you can plug your car into an extension cord connected to house current and keep the engine toasty on those cold winter nights. This makes much better cold starts, especially when it's below freezing, and it also speeds up the warm up time for your engine giving you heat from the heater just that much sooner. This listing is for all L28 engines. Your z will thank you for this one. We can also get them for the 240's, 260's, and 4 cylinder cars and trucks as well. Last update 12/11 |
