FAQ
Is this sold individually or as a set?This listing is for one (1) injector. Order the quantity you need for your build.
Do I need tuning with this injector?Yes. Competition-flow injectors require custom tuning and adequate air/fuel support (turbo and CP3).
Should I replace injector lines on an LB7?Yes. LB7 hard lines should be replaced anytime injectors are replaced to ensure proper sealing and reliability.
What other parts should I have ready?An install kit (gaskets/seals), new high-pressure lines, and if needed, screw-in cups for long-term sealing.
