New exhaust valve stem seal for all 1990-05 Miata engines. Also used for the intake valves on 1.6 heads.

Sold individually. 8 required per head on 1.8, 16 per head on 1.6. Included in our head gasket kits.

We only use & recommend NOK seals, the Mazda OE supplier from day one. We have seen far too many failures on generic (and cheap, in many ways) aftermarket valve stem seals. Given the amount of effort to change them, it's worth putting in the good stuff from the start!
