+1.

Well, except the MS6 part.

But I just really prefer the diaphragm design over the piston design in general. It lacks the potential for failure due to contamination or lubrication failure that plagues many piston-type valves. Keeping the sealing part separate from the flowing part makes a lot of sense from a design-reliability standpoint.

Now I'm kind of wondering how well my fake SSQV will perform under boost.. Can't decide which I wanna put on the miata.

I took mine apart and cleaned it all out, and put some graphite in it, but it was still really hard to move, so I took out the rubber O-ring that fit just above the horn and now it works really well. Doesn't seem to leak at all and it opens when it's supposed to.
