FAQ
Is this a set of 8 injectors?Yes. LML-200SAC-SET denotes a complete set of eight injectors for 2011–2016 LML applications.
Do I need a CP3 conversion or other fueling upgrades?With 200% over flow, most builds will require a CP3 conversion and additional fuel system upgrades plus proper tuning to supply and control the added fuel.
How does S&S ensure injector consistency?S&S uses proprietary nozzle honing and matches nozzles to ~1% variance per set, then verifies injector profiles across multiple pressure and energizing points.
Is there a core charge?Most distributors require a refundable core deposit for new LML injector sets; check your order terms.
