Recently, I purchased Autolite APP104 spark plugs for a Gen 2.
After a bit of searching, I've noticed there's a wide range of opinions regarding the gapping of spark plugs.
The first disagreement is whether or not the gap on a spark plug should be changed out of the box. From experience, gap specs exist for a reason and manufacturing and handling processes can affect those gaps. But I've also read platinum plugs can be easily damaged during gapping even when exercising care.
The second disagreement is if the gap should be changed out of the box, what should it be changed to ? For the APP104 on a Gen 2, I've seem numbers from .040 - .054.
Any thoughts ?
