GENUINE ZODIAC MANIFOLD FLANGES

These flanges fit Sportster 1990-2006, Evolution Big Twin 1986-2000 and Twin Cam 1999-2006, except 2006 Fuel Injected models. They come with the two required socket head screws and O-rings for use with stock and stock style manifolds. S&S manifolds must be installed with ZPN 236951 or 236952 O-rings. S&S O-rings are slightly thinner to accomodate the larger S&S port diameter. Use of stock style O-rings as supplied with these flanges may damage an S&S manifold.
