I'm interested in these IC spray kits, so I'll be keeping an eye on this thread.
I spoke to a mechanic a while back and he said to invest in the spray kits as i would see more gains from a water/meth kit fitted to my standard LCR IC's that would come on during boost, rather than getting a FMIC.
Bur aren't these kits about £300ish? So are they really worth it?
