V6 alloytec manifold for Holden Commdore, Rodeo, Colorado

Our revolutionary CPR6 V6 Commodore manifolds extract the best out of your Holden V6 alloytec four-valve engine, without the need for a thirsty V8. Our most recent dyno'd engine produced 422 bhp.

But you can easily put one on your daily drive and enjoy extra power and fuel economy.

Using years of cylinder head airflow research into volumetric efficiency, we've spent hundreds of hours at the flow bench to obtain the maximum horsepower from V6 alloytec manifolds.

We can work on just your alloytec manifolds to increase power, but we can go as far as you'd like to gain maximum powersuch as fitting Motec.

Our methods can be used on any alloytec V6 including Commodore SV6.
