  • Q: QUICK QUESTION  KGABBS 7 months ago

    Answer

    Is there a downfall to going ahead and running 2 steps colder in a 2011 WRX STI Hatch, even if I'm not currently very far from stock vehicle, but with plans on making big power in the near future?


    • A: These plugs will likely be too cold for your current set up. You are supposed to drop a step colder for every 75-100 HP gained. I would stick with stock heat range plugs on your current set up.

  • Q: E85  s20525xxx 11 months ago

    Answer

    Hi, there, I'm running one step colder atm with E85, and car is misfiring sometimes. I have already bought Okada coil pack, should I also run these plugs to eliminate misfiring? Car has 180hp over stock atm. Maybe also reduce the gap?


    • A: These might be a good solution for you. I would check with a tuner/shop to find out if they think this will fix the issue.

  • Q: compatibility  chipperoo55 1 year ago

    Answer

    i have a 2010 legacy 2.5l Turbo and have been using NGK SILFR6B 8, mods include turbo back exhaust, HKS power flow. I have dyno tuned the car. 1. can i change plugs to these after the tune or has to be before 2. are these compatible with my car. Thanks,


    • A: Stock heat range is likely the best option for your vehicle and those modifications, these two steps colder plugs are going to be for much higher power vehicles. If you do switch heat ranges doing so before a tune is recommended.

  • Q: Proper gap  Ruger 2 years ago

    Answer

    I know these plugs come pre-gapped but is there a specific gap setting for Sti's? I would think there is but I want to be sure before I install them


    • A: These plugs are pregapped at .032 which is similar to OEM but your tuner may have different recommendations for gap.
