The SPAL EF3521 Fan Mounting Feet Set is the professional choice for securing aftermarket electric thermo fans to custom radiators or custom shrouds. Rather than using cheap universal plastic "zip ties" that can degrade over time and damage delicate radiator fins, these genuine Italian SPAL brackets attach directly into the integrated slots on your fan's outer shroud for a rugged, permanent mechanical mount.

Key Features & Fitment Data:

• Part Number: EF3521 (SPEF3521)
• Quantity: Sold as a complete pack of four (4) brackets (enough for one single fan).
• Profile Style: Straight / Raised Profile (provides 4mm–6mm offset clearance from the core surface).

Installation Tip: For the ultimate professional cooling setup at NZ Air Filter, we highly recommend pairing these mounting feet with our premium Davies Craig digital fan switches or heavy-duty wiring relay kits to keep your high-amp performance fans running safely on the street or track.
