What is the difference in the R pump and the stock pump? Is it like a 20% increase in flow or what? Anyone that knows, I'd like to become educated on this, thanks in advance.

 

I brought an electric fan kit for my Lightning together with cooler thermostat and Cobra Pump.
This pump is supposed to be more efficient than the stock one.

You may find some info about this on the JDM site under coolling systems.

Good Hunting :santa:

 

The Cobra R pump is more efficient in that it takes less power to operate. However, I was told that is does NOT provide as much water flow as stock.
