he GKTECH replacement engine fan has been designed and engineered in Australia specifically for us with the intention of pulling more air than the factory item. Surprisingly, this was very easy to design and the design that our engineering firm came up with is based around the design of a propeller. It is a direct replacement clutch fan for the S13/180sx, S14 and S15 SR20 powered Silvia's/200sx's. Simply remove your factory fan (4 bolts) and install the new fan.
- Direct replacement of the standard fan
- Pulls 60% more air than the factory SR fan and pulls around 40% more air than the factory RB25 fan (a common upgrade)
- When tested on a dyno the new fan took less than half the time to cool down from 90 degrees to operating temperature (good for next time you're on the start line at the track)
- Only a slight increase in noise (barely noticeable)

NOTE: Can not be used in conjunction with Nismo engine mounts as the mounts raise your motor approximately 20mm's which will make our fan hit your radiator shroud (our fan is 15mm larger in diameter than the factory fan).
The fan is basically the same size as the oem fan, however had additional blades. The center of the fan where it bolts up the the fan clutch is actually metal, which was a nice surprise. The quality is better than I was expecting. GK tech has not disappointed me at all.
