    Anybody who is interested in this mod, keep in mind that icing can happen at above freezing conditions. This happens because venturi effect will cause temperature drop. Actually in carbureted cars this mostly happened at about 7c or 45F.

    So if temperatures drop close to freezing this might not be a good idea.

    Wanted to add some pictures as I've done this mod two years ago. Made the mistake of using a plastic coupler, it broke in half after a year so I replaced it with a metal/copper one seen here zip tied to a larger coolant hose. This is in conjunction with a custom intake. No real MPG gains but feels like it struggles less on hot days and is zippier on cold days.

    I'm thinking a ball valve in the line might be a good idea, easy to turn the flow back on if needed
