I've tried regular $5 Copper plugs, and tried all those Fancy Iridium ones and what not, found no noticeable difference. I have seen no real evidence that expensive plugs can make the motor run better or have more power.

Can anyone tell me what copper plug I should use on a stock ba xe6t and gap size.

I contacted ngk about having a copper plug. They sent back explaining that a copper plug is not suited for these engines as they were not designed to use one and that engine damage would occure. Also said they have seen the forums about using a copper plug and have no idea what plugs are being used as they don't make any..to suit in copper.lol

Thanks. So keep with a .9 mm gap? Would it affect fuel econamy etc?

I also contacted autolite spark plugs...even though they have a spark plug number for the xr6t in there catalog....they too said not to use a copper plug haha
