Taken from a site I was wondering if I have one?
"This is a close up of the ZXTuner upper intake. It replaces the factory upper resonator for less restriction in the intake system."

my 2.0 sohc dont have one I dont think.

no, we don't have one. And from what I've read, removing THAT resonator on the ZX2, actually HURTS performance. I forget why, but it's what I read.
