ngk ones usually come already around .027-.028, so you don't have to change it, but the stock ones will come with a smaller gap to be safer so you don't misfire it, so if you changed it to .025, you should be fine as long as you're not misfiring or anything, and your stock ones look pretty beat up, good idea that you changed them
Drives: 09 997 Carrera, 11 Cooper S, 11 Grand Cherokee
OEM NGK sparkplugs are gapped at around 0.022. i have changed at least 3 sets... I dont keep sparkplugs on the car more than 4000 miles...
The 1-step colder NGK racing ones that i was using before they were gapped at 0.024 and along with the Sun Hyperforce no misfires, only until recently where the gap had opened to a crazy 0.028 and the car was misfiring like crazy (thus and my poor track results until now...)
Couple of days ago changes my oil, filter and sparkplugs with a set of Denso IKH24s, 1-step colder than originals... They were gapped 0.022 or 0.023, i dont remember and the car runs like a champ again...
For EVO VIII people: Dont get confused... The IXs have completely different sparkplugs and sparkplug gapping...
