Spark Plug Brand + Gap?
Wanting to go with ACDelco Iridiums, but the ones I see on RockAuto are listed as being gapped to .043 inches, which doesn't jive exactly with the .04 listed in the 2005 2.2 owner's manual.
So my question is, should I
1) Buy and use them anyway, as they are,
2) VERY CAREFULLY change the gap on them to .04 inches,
3) Buy a different brand of Iridium (I see some attractive Denso Twin-Tips that claim a .04 gap), or
4) Buy the ACDelco Double Platinums on RockAuto with the .04 gap?
