Been searching around, here, google, other random forums and it seems like people are all over the place with plugs and gaps to be used on the SR.

Some of the things I've read are that the copper perform better, yet need to be changed more often, the opposite with the Iridiums. Some say completely stay away from the platinum plugs as well.

Gap ranges. I am aware that it depends on the level of boost, but throughout my search people give a bunch of diff for the appropriate "stock" setting. Some being .025 all the way to .038

Reason being for this thread is that I'm currently running NGK Iridiums (BKR6EIX) at a gap of .025 but I'm thinking of going with the NGK copper (BKR6E) with a gap of .030. I think my .025 gap may be relating to my little bit of a stumble and bad fuel economy.

Discuss.
