Tertiary fuel injectors on the S4
Has has anybody considered this idea? The openings on the secondary runners are a spot on fit for the fuel injectors. The hole lines up directly with the top ports of the end housings (6 port Intake). Just an idea for now, maybe change the positions on the secondaries to the new location for more direct injection.


i setup a friends car with 3 s4 N/A injectors with a AIC for high boost.
Had a fuel rail made and mounted on intake elbow on the charge pipe right before throttle body.
they had there own fuel pump and tied into an enlarged return line.
