FAQ — Do I need new injector feed tubes?
Yes, we strongly recommend installing new feed/connector tubes any time you change common-rail injectors. It helps prevent sealing issues and protects your new set from debris.
FAQ — What turbo and fuel system should I run with 250% injectors?Plan for a high-flow single or compound turbo setup and an upgraded CP3 (or dual fuelers) with adequate lift-pump supply and filtration. Match air and fuel to your power target.
FAQ — Are these truly flow-matched?Yes. S&S flow-matches nozzles and injectors to tight tolerances for consistent cylinder-to-cylinder fueling.
FAQ — Will these pass emissions?These are performance/race-intended components. Check and comply with your local and federal emissions laws before purchase/installation.
FAQ — New vs. Reman: which should I choose?New bodies offer a clean slate and maximum longevity for high-output builds. Reman can be a cost-saver; see our reman 250% option linked above for comparison.
