Intake Manifolds for S&S Carburetors – S&S Evolution® Engines

Zipper’s Performance Products stocks a large variety of intake manifolds for S&S carburetors. Manifolds for EV engines all have S&S’s ’oversize’ (1.880” O.D.) spigots on the ports that mate to the cylinder heads, and can be used on stock or oversize port heads without any adverse effects on air flow (requires #198-035 intake seals, sold separately). Evolution® manifolds have a vacuum nipple for a V.O.E.S. switch. Applications shown assume stock case deck height and stock to moderate-cut cylinder head deck thickness.

Stock cylinder length for EV Big Twin = 5.550″
Stock cylinder length for EV Sportster = 4.650″
