The AussieSpeed® Holden 6 cylinder 4 barrel manifold is suited to modified engines and has been used with LPG as well as on petrol engines on many Holden 186 and 202 engines. It has been used with blow through turbo chargers. Due to height restrictions and keeping the carburetor and air cleaner low on most model Holdens an increase in plenum height may see optimum performance on some engine combinations.

The Holden Aussiespeed AS0002  manifold has a plenum filler on the port floor, drop out grid and a divider in the centre of the plenum. The Aussiespeed manifold is 22.5cm wide at the widest point measured from the cylinder head face.

The manifold is equipped with a 1/4 npt vacuum take off on the rear of the manifold for brake vacuum and auto transmission fitting.
