Would the HOLDEN VE COMMODORE ORSSOM OTR COLD AIR INTAKE TO SUIT ALLOYTEC 3.6LT V6 be compatible with your 25MM COLD AIR INTAKE MANIFOLD INSULATOR TO SUIT ALLOYTEC VZ-VE 3.6L V6 ?

The VE V6 Alloytec Orssom OTR and 25mm Alloytec manifold insulators are compatible with each other (excluding MY09.5 vehicles). Ideally, though, you would need to tilt the rear of the OTR housing up about 5MM-10MM such that the air can more directly flow into the manifold. Alternatively, you could go with a 12MM Manifold Insulator.
