Air temp drop with WI

[350matt]

I realise that the answer to the above question will be 'it depends' but say I was running a reasonable level of boost +1Bar upwards and currently seeing 50-60?C air temp post intercooler. On a 250Bhp engine
How much would a 0.5mm jet drop this by?

I can see a 15-2C drop with a 0.5mm jet. Posisble more if you use M50/W50. Water is more effective for incy;onder cooling.
