Twin Electric Spal Fan Kit

Upgrade from the clutched mechanical fan to our modern electric fan shroud design. Featuring Italian Spal relays, wiring and curved fans, these Spal 14" & 16" fans move a combined 4,364 CFM and are automatically triggered to cycle on and off with the included thermostatic switch. This shroud only fits the factory ac radiators aka "tall & narrow radiators" does not fit the non ac "short wide radiators".

  • Superior fitment and usable surface area compared to the original factory plastic fan shroud.
  • Constant cycle rate, independent of engine rpm improves in town, low vehicle speed cooling and air conditioning in traffic, reduces load on the engine and improves mpg. 
  • Thermostatic fan control comes prewired and already installed to speed up engine warm up in cold climates and allows for a "cooldown mode" to cycle the fans without the engine running.
