sparkplugs and wires
i just baught bosch platinum plus sparkplugs with NGK wires that i am about to install tommorow morning and i was wondering if i made a good choice. I asked some guys around at canadian tire see what they think and personnaly they said that they wouldn't put NGK in GM cars and they would go more for Bosch. They are also half price of the iridium IX. So i got the bosch. The gap on the Bosch was higher then .040 so i put it at .040. Then i saw on the site that these spark plugs don't need to be gapped because they are preset. Is it true? because i gapped them to the recommended gap for a 2008 3.5L. Could it do any harm?
