In conclusion:
-Regular plugs for xB = meh-poor
-Platinum plugs for xB= better
-Iridium for xB= best

yes thank you indeed...though mine came pre gapped to .028??? and they are the same stock number listed on that chart.........also on another post some people reported better performance out of a .044 gap...Doug was one of them..........still kiciking around the idea, might run at reccomended gap for a couple tanke to find out what MPG i get, and then try to gap em at .044 and see what kind of difference i get out of them.........what else you think i should do? royal purple oil...K&N oil filter??......trying to get some more pep out of my box....still cant figure out why sometimes when i give it gass it boggs down then takes off....maybe my air intake is bringing in too much air?

Fresh new iridium plugs will work fine at the larger gap because of the much pointier center electrode making it easier to start and sustain an arc.
With fresh new plugs there very likely would be a slight advantage to the larger size spark giving a larger flame front and therefore better ignition.
The problem there is as the electrodes erode, the gap gets even larger and at some point the arc ignition is delayed, and sometimes even missing.
This is why for daily drivers the smaller gap is often recommended even though the larger gap is used for race cars that ALWAYS run new plugs...
So, .044 will give a larger spark for better fuel ignition and larger flame front, but will not be reliable for as log as a plug set to the smaller .032 gap.
Choice is yours as to which is most important: Maximum performance and changing plugs often, or long lasting plugs with slightly less performance. The actual different in performance between the two is unlikely to be that noticeable in an econobox.
Enjoy!

sometimes gap can make a differance when you have aftermarket intakes,filters,and such.........try it at .32 for a week and then try .42 for a week and then .44 for a week and see how the computer adjusts and which gives the best mpg and power......
on a lot of my older cars the gap at wider than stock gave me better bottom end fuel burn but worse mpg........not sure how a newer car will react since they have a learning computer and sensors to help.

thanks for all the advice, i know there are other posts out there about plugs, but i figured i would post up instead of weeding through all the other posts about it, in the minimal skimming i did someone mentioned getting like 40mpg on the iridium plugs...not sure how tangible this number is...but that would be nice!!...i'll def stick with the .032 for now
