FAQ
Is this injector street-legal?No. This is a competition-only, high-flow injector and is not intended for on-highway emissions-regulated use.
Do I need a bigger CP3 and lift pump?Yes. A 730cc injector requires a high-output CP3 (10mm/12mm/14mm as appropriate) and a quality lift pump to maintain commanded rail pressure.
Can I buy a full set?This listing is for a single injector. For matched sets, contact us or browse our LB7 injector sets and fueling packages on cppdiesel.com.
What else should I replace during installation?Always use new sealing/return washers and verify fuel system cleanliness. Consider fresh injector lines if contaminated or high mileage.
