I have a set of apex seals that a friend purchased for me. They are 3mm seals, but I dont know the application. I was going to list them on ebay but I wanted to know what they fit before i do. Does anyone know that application?


Part number N304-11-300A set of six

 

Apex seals seal the apexes(peaks) of the rotors. You need to have your rotors machined and grooved to fit 3mm seals.

I'll buy them off you for $5 + shipping.

Apex seals are highly sought after, if you have a turbo motor, you'll need them at some point. They are the single weakest part of the rotary engine.

And all previous 13b's from 74 up. And any 13b rotors which have been milled to accept 3mm apex seals, if you want to stay with mazda oem apex seals.

 

they have superceeded it so they fit every 73-85 13B

 

I have a 91turbo 13B do I need to mill the rotors to make them fit??

 

Yes.
All 13B motor from 1986 and newer all ran 2mm apex seals.
If you want to use these apex seals, you need to mill your stock rotors.
