Description

The Flyin' Miata exhaust/intake valve stem seal is a direct replacement for your Miata's engine. This seal is designed for the exhaust valves on all 1990-2005 NA and NB Miata engines, and also fits the intake valves on 1.6 liter cylinder heads. Crafted by NOK, the original equipment manufacturer (OEM) supplier to Mazda, these seals are chosen for their reliability and performance. Given the labor involved in this procedure, opting for reputable seals is a worthwhile investment. Each seal is sold individually. For 1.8L engines, 8 seals are required per cylinder head, while 1.6L engines require 16 seals per cylinder head. These valve stem seals are also included as part of Flyin' Miata's comprehensive head gasket kits.
