Unleash Your Holden V8’s Potential with the CPR8 Manifold

With over a decade of R&D, Performance Manifolds has transformed Holden V8 engines with the Australian-made CPR8 V8 LS manifold, delivering up to 100 horsepower gains for VZ, VE, and VF Commodores.

Maximise engine efficiency with our Holden V8 plenum upgrade, designed to enhance airflow and harmonic dynamics for peak performance.

The CPR8 manifold optimises the airflow potential of LS3 cylinder heads, achieving up to 490rwhp from a standard 6.0l LS engine with no ported heads—just our CPR8 manifold, cam, and exhaust.

For even more power, pair the CPR8 manifold with ported heads and 410 cubic inches for up to 750 hp at the crank without forced induction.

Upgrade to the CPR8 V8 manifold and experience unparalleled performance.
