I need to refill the intercooler spray on my STi8. The manual says to use "pure water". I guess this is to prevent "furring" and chemical build up in the spray system.

What does everyone else use ? Do you top it up straight from the tap ; use de-ionised/ battery top water, or should I just pour in a few bottles of Evian :-)

Cheers

Just put water outta the tap.... i think the "pure water" means you don't need antifreeze or detergent etc in it!

 

Always just put tap water in! Good job as well as it goes through it at this time of year!!!

 

Yep, just normal tap water will do. In this heat I've had to fill the water every 3 days!

 

Hmm I've done 40,000 in 12 months and never put in a drop.

 

Best bet if you are worried about using tap water it to use one of those Britta Filtered kettle's or jug's.

 

I use water you have to throw away when you change the filter.
