I have a bad acv for my 91 n/ but the the valve is dry rotted.
I have a automatic acv that could use parts from

 

NA? the S5 has the pickup for the 6 ports, so the whole valve won't work, but you can swap the guts

 

thank you! I took his part from an automatic ACV 88

I only need this weird part since mine is rotted

the automatic hasa spring on it. Mine never had the spring. Should I also transfer the spring to my 91 acv?

 

nah just keep it like it was

 

I have a 91 n/a 5 speed transmission ACV. Im using the ACV guts from a 88 n/a Automatic. Just that weird pink plunger.
everything else works fine. The solenoids work when they should.
I wish there was an easier way to rebuils these Air Control Valves. New acv parts are expensive and hard to find.

 

Mazda has a kit now, but its for the FD and S5 FC turbo FDXU-13-991
i see it for sale on Yahoo Japan Auctions, but nobody else seems to know about it

 

wow! Thats awesome! Love how we find out about parts. Now we just need someone to compare them. Seems like they should be the same.

 

Has anyone been able to confirm if we could also use this plunger as a replacement for n a?
