What is the difference between the MACE Performance CPR6 Intake Manifold for Holden Calais VE Alloytec LY7 3.6L V6 and the stock manifold?

The CPR6 manifold is manufactured from high-quality automotive-grade cast alloy and is designed to deliver significantly better breathing and airflow compared to the stock manifold. It provides the Alloytec V6 with a smoother, cleaner intake path, resulting in power gains of up to 11%. While there may be a slight reduction in low-end power, the CPR6 offers noticeably improved performance at higher RPMs, allowing the engine to breathe far more efficiently.
