These injector seats are required when converting an aftermarket injector that uses a 14mm lower O-ring. Please specify which engine you need these for in the selection bar. These engines include the 2JZ-GTE and 1JZ-GTE Non VVT-i as well as the 2JZ-GE. There are many other engines not listed. They simply "pop" into the intake manifold (1 required per injector). They seal into the machined injector counterbore using the included FKM O-ring. The injector seats are CNC machined with a common 14mm bore for the lower injector O-ring.
