Special Big Port Manifold Gasket

Special Big Port Manifold Gasket


The Datsun Spirit  & Jenvey Dynamics collaboration manifold is made to go with the DSI big port gasket.


These manifold gaskets were created with the same exact port locations and sizes as the NISMO gasket which has long been discontinued but is known for the best port locations. Other aftermarket manifold gaskets have ports in the wrong locations.


For our STD and SPL heads, you need these gaskets.
