The Racer X Fabrication spal fan shroud was designed to bolt directly the Greddy style side mount intercoolers. The fan shroud works with the high air flow Spal fan part number: 30100392 (9” Spal fan). The fan shroud is CNC cut from 5052 aluminum sheet and then formed using a CNC press brake. The shroud uses clinching studs instead of rivet nuts. This makes installation much easier, as the fan sits on the studs and does not require you to hold it in position during installation.
