Offenhauser C Series intake manifold.

Offenhauser C Series intake manifolds fill the gap between stock and competition setups for 4 and 6-cylinder cars and pickups. They improve torque in the mid and upper ranges, with power bands that span from 2,500 rpm to more than 7,000 rpm. Smaller applications use Holley 5200 or Weber 32/36 Series 2-barrel carbs (see adapter 5095 or call for details).

Fits 1981 - 1988 Jeep with AMC 258 (4.2L) inline 6
