FAQ
Is this a direct-fit LB7 injector?Yes, the 502COBRA0256 fits 2001-2004 LB7. It is a competition-calibrated unit and is not intended for stock fuel/air systems.
Do I need to replace the injector lines?On LB7s the lines commonly corrode and can contaminate new injectors. We strongly recommend new high-pressure lines during injector replacement.
What supporting mods are required for 860cc?At minimum: quality lift pump, stout CP3 supply, large turbo(s), race-grade filtration, and custom tuning to manage pulse width and rail pressure.
Can I mix this with different-flow injectors?No. Keep all cylinders matched to the same part number and flow for balance and engine safety.
