This is the OEM manufactured that makes majority of all gaskets for Japanese vehicles so I can say with confidence it's good quality. I rated 4 stars however because one of the holes in the gasket, where the bolts go through from the valve cover, didn't have the hole punched out all the way. I had to cut out the rubber which took me no more than a minute. I haven't driven the car since the install but it fit like a glove.
