PART NUMBER: 61-2636
Imported from Mazda Japan, not a knockoff gasket like others are selling.
Also works on 2004-2005 Mazdaspeed Miata as those cars have a non-VVT 99-00 head on the turbo engine.
Note: This gasket has all four spark plug rings linked together, as was the norm for the 94-97 gasket. For 1999-2000 engines, just snip the link between the #3 and #4 ring with a pair of scissors to make the gasket look like the image above.
