In stock now - NEW DESIGN flows even better than our Ultraflow Cullen Special
PT#AS0167 - AussieSpeed Holden 186 and 202 Red motor 2 barrel performance manifold. AussieSpeed has done it again we reworked the popular Ultraflow 12 port Holden manifold originally made by Kit Cullen however it was still not quite as good as we would have liked it for eveness of fuel distribution from port to port, so we incorporated everything we have learnt from the 4 barrel manifold development and put it into this new two barrel manifold.  This AussieSpeed version features new design 3 & 4 runners and we altered the plenum for improved air speed and fuel distribution to provide for even better cylinder to cylinder filling of the air fuel mixture. Flow bench tested design, true bolt on perfromance straight out of the box.
Great for street engines and speedway classes limited to a 2 barrel caburettor.
