Hi guys, i"m doing my pi head swap this weekend and i don't know what spark plug to use. Should i use the ones from 2004(my new heads are 01-04 romeo)? Some help would be greatly appreciated.
I would think the recommended stock plugs (02-04) will work just fine unless you make other changes as well.
NGK TR-6, it's a colder spark plug which is what you will want in a PI swap since you have raised the compression.
Ok thanks, i think i"m gonna go with the ngks
im using the tr6 plugs and recommend them, good plugs
