SPAL 16" Thermo Fan Rubber Mounting Gasket Shroud Seal (EF3552)
The SPAL EF3552 is a premium, heavy-duty molded rubber mounting gasket specifically engineered for 16-inch SPAL thermo fans. Designed to sit directly between the outer shroud profile of the fan and the flat surface of your radiator core or custom aluminum fan shroud, this gasket creates an airtight, flush mechanical seal that eliminates airflow bypass. By forcing 100% of the fan's suction directly through the radiator fins rather than drawing passive air from around the edges, this simple upgrade drastically increases overall static pressure and cooling efficiency. It also provides an additional 6.35mm (1/4") clearance buffer from the core while acting as an excellent anti-vibration dampener to protect your aluminum radiator from structural fatigue under harsh track, drift, or off-road conditions.
