BALANCE TUBE O-RING SET (90-96 NISSAN 300ZX)

Set of the (3) rubber o-rings that go between the balance tube and the upper intake plenum.   The original o-rings become hard and brittle over time often flattened and incapable of a strong seal.  We recommend replacing these o-rings to provide an air tight seal against both the vacuum and boost pressures that they may be subjected to in a Z32 intake manifold. 

Includes (2) larger diameter o-rings and (1) small.
