These engines include the 2JZ-GTE and 1JZ-GTE Non VVT-i (above) as well as the 2JZ-GE (shown below). 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 Viton O-ring. The injector seats are CNC machined with a common 14mm bore for the lower injector O-ring.
