Radium Engineering Injector Seats Mazda Top Feed Fuel Rails

Radium Engineering Injector Seats - Mazda Top Feed Fuel Rails

These are the same machined aluminium injector seats Radium Engineering uses in its fuel rails for the Mazda / Eunos Cosmo and RX-7 rotary engines. They convert the OEM 16mm injector counterbore to 14mm, which suits the lower O-ring on most popular aftermarket injectors, and simply pop into the OEM injector bore.

They are designed to work with or without the OEM injector diffusers installed and seal to the machined counterbore with the included FKM O-ring. The seats suit both the primary (iron) and secondary (intake manifold) injector locations, and the taller primary seats extend the O-rings past the air assist holes in the irons.

Note: Sold individually – the 13B-RE and 13B-REW need 4 (2 primary + 2 secondary) and the 20B-REW needs 6 (3 primary + 3 secondary). Most aftermarket lower intake manifolds are already machined for 14mm secondary injectors, so check before ordering. Installation by a professional is recommended.
