    • Q: Stage 3 competition clutch   Brendan red wrx3 years ago

      Will this fit with a stage 3 competition clutch?

        A:  This would pair with a Competition Clutch, but we would not recommend the Prolite for any street/daily use.

    • Q: Setting off CEL  Chubaru243 years ago

      I did some research and am finding that this usually only sets off an CEL when paired with a lightweight crankshaft pulley. since im still running the stock pulley, do you know if this alone would set off a CEL? thanks

        A:  This flywheel paired with the stock crankshaft pulley should not cause a check engine light to turn on.

    • Q: CEL light  jonsVTECpower450166 years ago

      so its states it may cause a CEL, if I was open-sourced tuned with it, would it still cause a CEL?
      • 0 of 0 people found the following answer helpful

        A:  An open source tune can turn the check engine light off, but you can still experience misfiring.
