PT#AS0009 - AussieSpeed Holden 202 Black Blue 4 barrel performance manifold.12 port wide runner manifold features new design runners for improved air speed and fuel distribution, shaped plenum and divider to cylinders 3 & 4 to equalise fuel distribution to all six cylinders. 100% plus improvement over all previous Holden six 4 barrel manifold designs ever made by anyone, this is made specifically for the 12 port Holden head although you may notice there are no port dividers on the head side. There are no port dividers in this manifold like our competitiors products because they were proven not to work by us when dyno testing old designs, we found they actually hindered performance. AussieSpeed must be congratulated for their persistence and continually striving to achieve a better result. Designed for hot street engines, lpg gas engines ,blow through turbo & competition engine with modified head & camshaft, & free flowing exhaust.
