    Is there any downside to removing the preheater setup except for taking a little longer to warm up?

    I assume that the preheater your talking about is the air intake hose that takes warm air from around the exhaust manifold. I disconnected mine, and haven't seen any problems yet. I do live in Phoenix, but I have had my Jimmy in the snow and didn't really notice any differnece in starting up there either.

    Sorry it took so long, but I had football practice. No I have not felt any decrease in power, and in theory it should help power because you get cool dense air to the carb instead of warm air. I believe I also read somewhere that it sucks in warm air if the outside temp goes below 80 degrees. I have no intension of ever reconnecting the system. Its a useless potentially power robbing emission POS.

    I agree with hossbaby50 but that is great in AZ. and SC. but here in NY when then temp is below zero you need all the help you can get to warm the truck up

    Thats what I was thinking. I'm gonna do that as soon as I have nothing else on the truck that could use the money.

    Yeah, colder air is denser and allows for more fuel to burn. Basicly.
