I thought about doing A/W on my setup, but decided A/A style instead
1) Simple install
2) no water leaks, no pumps to crap out, ect.
3) Even tho I don't street/daily, water will warm up eventually and not cool as well.. at the track you ice it down and nice gains in cooling.
m90 IC stinks.. ditch it and go A/A and move on with things.
