Holden VZ Calais V8 Custom Shroud & Twin Spal Fans

Upgrade your Holden VZ Calais V8 cooling system with the Custom Shroud and Twin Spal Fan Kit. This setup improves airflow and cooling efficiency, helping your engine maintain stable temperatures during daily driving, touring, and performance use.

The custom shroud directs airflow evenly across the radiator core, increasing heat dissipation and reducing heat soak under demanding conditions. Twin genuine Spal fans deliver strong, consistent airflow for reliable cooling performance, especially at low vehicle speeds and under load.

This shroud also uses an integrated air bleed system to improve airflow management. At idle, the flaps stay closed so the fans pull air through the full radiator core for maximum cooling efficiency. At higher speeds, the flaps open to allow unrestricted airflow through the radiator, preventing air from becoming trapped behind the shroud.

Each unit uses durable materials and a powder-coated finish for long-term reliability and a clean fit. The direct-fit design suits both standard and modified V8 Calais models.

Please note: This part is built to order and requires a 1–2 week lead time for fabrication and powder coating.

This shroud utilizes a pair of high output 12″ & 13″ fans, pulling a combined 3034CFM.
