Aussiespeed Range Of Holden 6 Cylinder Inlet manifolds
Aussiespeed Holden six red and blue motor manifolds offer true horsepower out of the box, these manifolds are not just a bracket to hand another carb on the side of your engine. The Aussiespeed range of Holden 6 performance manifolds offer high velocity port design semi tuned length intake runners.
Our latest Holden 6 cylinder 4 barrel manifolds have new design features including tall fuel injector mounts, both north south and east west carb position mounting. There are 3 models with the first being the
AS0002-16 to suit red motor 9 port cylinder heads.
AS0009-16 being the big port to suit 12 port black and blue motor cylinder heads and the latest released in october 2016.
The all new AS0003 it is a small port manifold to suit 12 port cylinder heads for engines looking for good throttle response and is ideal for mild street engines  that operate between idle and 5000 rpm.

Aussiespeed has a very extensive range of performance and dress up stuff for Holden 6 cylinder engines.

AS0169 Aussiespeed Holden 202 2 barrel black,blue and yella terra aluminum 12 port head manifold NEW DESIGN
The ultimate Holden six manifold has features we have used in our 4 barrel manifolds for Holden 6 cylinders, We havent just changed the flange to accept a 2 barrel manifold the plenum shape,runner volume,runner length were designed to produce the #1 performing Holden six 2 barrel manifold .
Pictured is the new Holden six manifold with Holley 500 CFM 2 barrel Carb & AussieSpeed 9 inch polished finned air cleaner. The Red motor & blue motor manifolds use different port heights. You simply can not make a 2 or 4 barrel manifold that fits both engines & gives maximum performance.

This picture shows a ceramic coated Aussiespeed manifold the divided plenum of the AS0167 and AS0169 Aussiespeed 2 barrel Holden 6 inlet manifold, The unique plenum is not unlike to the type used on our 4 barrel Holden & chevrolet inline 6 cylinder manifolds. The New AussieSpeed Holden 6 2 barrel performance inlet manifold is 195mm wide from runners 3 and 4 to the outer ear mounting pads.



  Photographer and Street Machine owner Rick found that the power he gained by switching to the AS0167 2 barrel manifold greatly increased his terminal speed and 1/8 mile times.

The Ultimate Holden performance manifold suit 179,186,192,202 & 208 straight sixes, High velocity ports. The Aussiespeed water heated plenum can be fitted for better cold engine running,Produces wide power band over entire rev range. The all new Holden 6 manifold is like no other Holden six manifold, unlimited horse power potential with modified cylinder head . Accepts holley squarebore carbs. 450 vac, 465 vac, 600 vacuum secondary & double pumper Holley. The unique plenum design produces torque like you could only wish for. Others have tried and we did also, you can not make a manifold that gives maximum performance on both red and black motor Holden engine, With different port dimensions and cylinder head designs this manifold has been tested and proven to be the best Holden red motor 4 barrel manifold available. The manifold has be used on mild street engines to all out competition race engines. Works in dual fuel applications also. The manifold from the head face to outside of the plenum is 235mm

Many hours have gone into the Aussiespeed range of intake manifolds the AS0002 has under gone changes to the current model shown above.

The new Yella terra aluminum cylinder head The head is much lighter than the std cast iron head ,produces more horsepower out of the box than std iron head by up to 50 horse power, is about a 3rd lighter accepts up to 450 thou valve lift & is available in both 72cc for turbo & supercharged holden sixes or 56cc combustion chamber. valve size for both cylinder heads are the same size.

Advance plenum design



Cast fuel injector, nitrous oxide bosses


The Aussiespeed 12 port 4 barrel manifold features high velocity port runners, To make more air speed for a broader power band & torque curve . Port size allows for bolt on with unported head.
Holden 6 cylinder using AS0009 4 barrel manifold with procharger supercharger made over 400 horsepower, the engine was extensively modified and engine was built by Bullet Cylinder Heads.

The Aussiespeed Holden six blue/black motor 4 barrel performance manifold has a unique design plenum that will work on mild street engine to & all out race engine,The plenum filler is to boost air speed & due to its shape works in upper RPM to aid in fuel/air distribution. due to the manifold runner & plenum volume the manifold has a larger volume than other 4 barrel manifolds & the shape over comes out of the hole bogging when used with a tuned carburetor & matching ignition system. For drag racing application the plenum improves 60 foot times & in our testing our test engine the ET was quicker with the plenum filler.
