Ok so I am a little confused, my evo did not come with a manual so I was just wondering, is there a separate windshield fluid tank for the front and back windows? Is that what the black tank directly behind the driver side headlight is?

 

no that one is for your intercooler sprayer.

 

^^ correct and the rear is for the windshield washer fluid.

 

Thank you, I thought that might be it too. I am a noob to this stuff so how does the sprayer work? What do you fill it with and how much do you fill it with, there appears to be come blue fluid in it now..

 

There is a switch near your cup holders. One is an auto setting(up) the other is a manual setting(down. It will spray as long as you hold it down) Water is what most people run, but not during the winter, haha. I dont think that is does a thing, so i rerouted my nozzle and now i squirt cars in front of me and my friends.

 

fill it all the way with washer fluid. water alone will work if the temps wont freeze it. it has a drain to so when its overfull dont think you have a leak

 

what does it recommend to fill it with in the manual?

 

Also, could someone tell me how the automatic part of the sprayer works? does it do it only when you floor it or what? How much of an advantage does using the sprayer give you?

 

water is fine, but for winter or freezing conditions fill with washer fluid as said before. its really not that much of an advantage...
