New Composite Intake Manifolds for "D" Style Carbs.
Since S&S has stopped making or selling any parts for the Nitro Carburetors, HRP has been busy designing and manufacturing new parts for these carbs. The intake manifold was just one of the parts S&S obsoleted. Hawaya Racing now offers a Composite Intake manifold that designed to fit our Derringer racing engines. This new manifold is extremely light, Nitro resistant and tough as nails! These new intakes will now be OEM for our Derringers. Contact HRP for more info.
