The SPAL EF3500 (VA07-AP7/C-31A) is a high-performance, 9-inch 12V electric thermo fan engineered for optimal engine and auxiliary cooling configurations. Generating a powerful 624 CFM of airflow, this straight-blade puller fan mounts behind the cooling core to draw air through efficiently, making it a favorite for custom motorsport builds and tight radiator setups across NZ.

Part Number Cross-Reference Matrix

For seamless replacement or upgrading of your existing cooling unit, the EF3500 is the correct match or high-output alternative for the following references:

• SPAL Global Model: VA07-AP7/C-31A (US Factory Part # 30100392)
• Alternative Trade / SKU References: EF3500 / SPAL-EF3500 / SPEF3500
• Mounting & Dimensional Alignment: Shares physical footprints with the VA07-AP8/C-58A and VA07-AP12/C-31A series
• Pusher Twin Counterpart: EF3501 (If your setup requires front-mounting to push air into the core, use the EF3501 model)

Applications: What This Fan Is Used For

The EF3500 9" fan is selected by professional Kiwi fabricators and performance tuners for these common high-demand configurations:

• Primary Radiator Cooling: Perfect size for small-displacement engines, karts, micro-sprints, and project cars with limited space behind the main radiator core.
• Secondary / Auxiliary Cooling: Often paired alongside a larger main fan on custom shrouds to maximize airflow on drift or track cars facing extreme thermal loads.
• Large Fluid & Transmission Coolers: Provides massive airflow across oversized aftermarket transmission and oil cooler cores mounted in rear setups or inner guards.
• Off-Road & ATV Systems: Features a fully sealed, waterproof and dust-proof motor that thrives in harsh dirt, mud, and water environments.
