It has been difficult to find exactly what they should be gapped but the range I've found is .022"-.026". Most people seem to do .024". I went ahead and did .022" and have been running JB4/map5 much better than my gapped stock plugs. I would recommend getting the 14mm BMS Billet Spark Plug Gapper with the feeler gauge.
I have the HKS for the 2.0T and .022 was recommended. .024 should work but like "Spaceme17" says, you don't want to install them without the proper gap......m-i-s-f-i-r-e......not good. if you have the 3.3, gap should be about the same. Gap tool is makes it easy
