Does anyone know what the Mazda part number is for the manifold gasket? It's the gasket AFTER the manifold and BEFORE the cat. I ask because the girl at the parts counter at the dealership always has a hard time locating it for some reason, although you'd think they'd know by now after as many as I've gone through...

 

n326-40-305 i think it superceeds to n386-40-305 but i'm not sure off the top

 

you can find it from mazdatrix or any of the online parts catalogs
