    Good product no problems... 5 years ago
    5out of 5stars

    Good problems no need to blame on the product because it is a pain to install the plugs on Subaru vehicles. These are great replacement for stock plugs that cant handle all the power adder mods.

    Plugs simply didn't give enough fire to start my car. I was very disappointed. Switched to stick NGK plugs and started right up. Was a huge hassle because STi engines are a pain in the ass to change the plugs on.

    Big difference on the response, especially when paired with my okada plasma direct coils, a must have for your sti or wrx and you can get the coils from RSD. RSD once again the BEST!!!

    QUESTIONS & ANSWERS

    • Q: Gap Size?  Synapse3 months ago

      I have found conflicting info -- some sources say to use the stock spark plug gap size of 0.028in / 0.7mm, others recommend that you do not ever gap iridium spark plugs. Any ideas?
      • 0 of 0 people found the following answer helpful

        A:  It is not ideal to gap iridium spark plugs, as it risks damaging the spark plug's electrode. These will be pre-gapped at .032.

    • Q: Plug Heat Range  Ozpic5 years ago

      Why one step colder ? this is an issue that has always confused me as people I have spoken to seem to have a different take on the subject,so if some one can clear this up without getting to technical I sure would appreciate it.
      • 2 of 2 people found the following answer helpful

        A:  The idea is to go one step colder per 75-100HP you add. This helps prevent predetonation and knock.
