Just replaced the factory spark plugs with some platinums (AP104s) and I set the gap at 51. What is the recommended gap for a 2006 2.0? If the gap should be .55, should I pull them and re-gap? What if anything can I expect if I leave them be?

... Just checked my owners manual.. turns out the recommended gap is .51 So what would a .55 gap gain me as some of you have recommended? Just curious....
