WRC Water Injectors on front crash bar????, Feature I didn't know about??!! Options

[Tech-Nics]

When I got my GT-Four bumper I thought it was an ordinary GT-Four front bumper until I noticed there was injectors in the inner side of the crash bar. At first I did't even know what the hell those were for. So I just left them in and installed my bumper. Just recently I was looking around and I came over the information I was looking for regarding it. Apparently the WRC versions came with a "Intercooler spray" that is built onto the inside of the crashbar. This is where I got the info from:

http://www.gtfours.co.uk/what/wrc/list/wrc_goodies_list.htm - Apparently it was supposed to connect to the headlight spray unit, but that confuses me cause I thought that the head light spray was only offered on EDM model Celicas & wasen't the WRC versions only released in JDM?

The site mentioned above doesn't really explain enough to me about this feature. If there is someone who knows more can you please explain more about this? I mean there are three water injectors were does it spray the water too?

Here isa crash bar RPMGarage has for sale with the same feature: http://rpmgarage.com/new/detail/?tid=14894

Thanks for any info thrown my way.
