These are the same machined aluminum injector seats used in Radium fuel rails for Mazda/Eunos Cosmo and RX-7 rotary engines. They are required when converting the OEM 16mm injector seat's counterbore to 14mm which is more common with popular injector lower O-rings. They simply "pop" into the OEM injectors bore. They were designed specifically to be compatible with or without the OEM fuel injector diffusers installed. They seal to the machined injector counterbore using the included Viton O-ring.

They can be used for the primary fuel injector iron ports (shown above).

They can also be used for OEM intake manifold secondary injector ports (shown above).

NOTE: most aftermarket lower intake manifolds are already machined with 14mm lower injector O-ring ports.

FEATURES:

Compatible with or without OEM diffusers
CNC Machined Billet 6061 Aluminum
Type-II Black Anodizing
Laser Etched Logo
Boost and fuel compatible Viton O-ring
SOLD INDIVIDUALLY:

13B-RE requires 4 total (2 primary+2 secondary)
13B-REW requires 4 total (2 primary+2 secondary)
20B-REW requires 6 total (3 primary+3 secondary)
