FAQ
Is this the correct injector for my LLY?Yes-0986435504SE series injectors fit the 2004.5-2005 LLY. The R6 variant is the 38 LPM high-flow option.
Do I need tuning with 38 LPM injectors?Custom tuning is strongly recommended to optimize timing, pulse width, and rail pressure for drivability and emissions control.
What else should I replace during the job?Install new seals/lines with an injector install kit and address any fuel filter head leaks to protect the new injectors.
Can I mix different LPM injectors?We do not recommend mixing flows. Use a matched set for balanced cylinder fueling and smooth operation.
