Does anyone know the volume of the factory, boot mounted, intercooler water spray tank,for a 07 WRX?

I cannot get it confirmed thru Subaru (yet!) or by reading my car manual.

I have a feeling that is is around 4 litres, but not sure.

I have made my intercooler spray automated and run thru a shit load of water and before upgrading the tank I want to know what I am upgrading from.

w * h * L = volume.

valid if it was a square unit... but its not.

Best bet is to get a measuring jug when its empty and measure how much it takes to fill up. I have put in 2 litres before, and it was still about a third full. so my guess is 3 litres

Because it is under the boot trim I cannot see when it it empty - this makes a zero starting point hard.

The manual says that the IC dash light activates when 400 ml is left. When the light was on I put ~3.5 ltrs into it.

All I really have is it is definitely less than 5 ltrs so far.

Thanks for the advice and notes on experience

This ones 12 litres



This ones 4.5 litres from my02

4L afaik

yeah get the sti spec c 12L tank. bolts to the back of your seat.

Syphon the water out from the tank

Then fill it up with a measureing jug.

The SPEC-C has a 12L tank as showen ^^ the Stock STI has a 4.0L

this may sound like a stupid question.

but with the spec c tank, do you ever hear water sloshing around when turning, going over bumps etc?
