With my 350z, I had done a bit of reading about purple ice versus water wetter by red line. You will find mixed reviews on each, some people claim purple ice gunks things up and WW works great, then you hear the exact opposite out of someone else.
Anyway, I ended up trying purple ice since I used their oils and got a discount when buying more stuff. It lowered my temp around 5 degrees. Nothing to write home about, but I guess every little bit helps.
I have heard of people claim up to 20 degrees, I'm not sure how that's possible, other than to say it must be very car dependent.
