Helpful Notes
- Tuning and airflow are mandatory. Match turbo(s), CP3 supply (often dual CP3), and lift pump volume to injector size.
- Late-5.9 (2004.5+) injectors differ from early-5.9 (2003–2004). Verify by VIN/ESN and build date.
- Competition use only where applicable. Core charge may apply on some builds.
FAQ
How much power can King Cobra injectors support?They’re designed for serious competition builds and are the largest of the Cobra series. With the right air system, dual CP3s, and proper tuning, they are used on 1,500–2,200+ HP builds. Results depend on the entire combo.
Do I need a dual-CP3 setup?In most cases, yes. King Cobras demand significant rail volume. Dual CP3s (or a high-output stroker pump plus strong lift pump) are recommended to maintain commanded rail pressure.
Are these injectors daily-drivable?They are competition injectors. Streetability depends on tuning and the rest of the hardware, but idle quality is excellent for their size when calibrated correctly.
Is there a core charge?Some listings note a refundable core charge; check your specific order details at checkout.
