DESCRIPTION
Header Gasket 1999-05 This gasket is required for correct fitting of a header/exhaust manifold on the 1999-05 (1800cc) Miata. This gasket can be used as a replacement for use with the stock exhaust manifold. (Note: This gasket is dimensionally identical to the 1994-97 (1800cc) gasket, but one side of this gasket is "flat" and does not contain the embossed areas around the exhaust ports.)
BRIAN'S APPLICATION NOTES: Note that factory gasket is a stainless steel plate just like this replacement and most of the time they can be used again and again...they do NOT need automatic replacement for adding a high performance header.
