DESCRIPTION
This gasket is required for correct fitment of a header or exhaust manifold on the 1990-93 (1600cc) Miata. Both an outer gasket and inner gasket are required. (Outer gasket = 3 layer, Inner gasket = 1 layer) These gaskets can be used as replacements for use with the stock exhaust manifold.
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.
