Neat little hp/tq increase at less than $1.00 cost!

The only problem with this is if you live in snow country the manifold will freeze up and it will run like crap when that happens. My VW would do that all the time. It would freeze from the carb to the heads. Then I would stop and watch as it unfrosted.

The vaporization of fuel, combined with the expansion of air as it flows through the carburetor, causes a sudden cooling of the mixture. The temperature of the air passing through the carburetor may drop significantly within a fraction of a second. Water vapor in the air is “squeezed out” by this cooling and, if the temperature in the carburetor reaches 0° C (32° F) or below, the moisture will be deposited as frost or ice inside the carburetor passages. Even a slight accumulation of this deposit will reduce power and may lead to complete engine failure, particularly when the throttle is partly or fully closed.
