Nissan Serena C26 Intake Manifold Gasket


















The Nissan Serena C26 is using the MR20DD engine, it seems their engine gasket should be roughly interchangeable with the MR18DE or MR20DE engine, but the manifold system in this MR20DD engine have little modification from the MR20DE type.

As the Nissan HR and MR series of engine, is design as such once you change the rocker cover gasket, you may need to change the intake manifold gasket as well, the MR20DE and MR20DD engine is sharing the same type of rocker cover gasket but not the intake manifold gasket.

The photo show the intake manifold gasket for Serena C26 model which carry the OEM part number 14035-1VA5B.
