8007-2-Z Manifold nuts, plumber style

These Colony plumber-style manifold nuts are a must-have for anyone working on pre-war and early post-war Harley-Davidson engines. Sold as a pair, these zinc-plated nuts provide a reliable connection for your intake system. They are engineered to fit 1934 to 1948 74 and 80 cubic inch Sidevalve models, 1936 to 1939 61 cubic inch OHV Knuckleheads, and 1940 to 1946 45 cubic inch WLD models. Replacing worn or corroded manifold nuts is a simple way to prevent intake leaks that can cause lean conditions and poor idling. These nuts are a direct replacement for OEM 27050-30, ensuring your vintage machine stays period-correct and road-ready.
