Pro Products Crosswind Dual Plane Manifold - SBC 1,500-6,500 rpm
$155.95
The new CrossWind Dual Plane Manifold AIR GAP Style is a special version of the
52020/52021. While it is the exact same height, it features an
open area under the plenum chamber. This provides for a flow
of cooling air which keeps the temperature of the air/fuel charge
lower, thus producing more power and torque. The interior plenum
and port design are identical to the 52020/52021 and will provide
somewhat better overall power than the 52020/52021 due to the
special design.
