    I need to change my plugs sometime this weekend and I can't seem to get a ton of info on what would work best in an ej20G engine. So far denso sells the IK20 and their site seems to recommend a .044 gap and bosch sells the FR56 which says EJ20G on their site, but is unavailable in stores i called. I cant find either one of these plugs at checker, autozone etc. anyone have any ideas?

    sorry but this is OT: why do turbo cars run colder plugs?

    .044 seems to me like it would be WAY too much gap for a boosted engine, which I'm recalling that you now have.

    For reference, most everyone recommends .028 for modified WRX's.
