These are the same machined aluminum injector seats used in Radium fuel rails. They are required when converting the OEM side feed fuel rail to top feed in popular Toyotas. These engines include the 2JZ-GTE, 1JZ-GTE, and the 3S-GTE among others. They are many other engines not listed. They simply "pop" into the intake manifold (1 required per injector). They seal into the 22mm 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.

Installation

Thoroughly clean out any dirt or debris found in the intake manifold injector seat bores. Next, lubricate the Radium injector seat O-rings with engine oil. Press the Radium injector seats down firmly into the intake manifold injector ports until fully seated. If necessary, use a small rubber mallet.
