Spark Plug Question
b6 1.8TQ apr stage 2+ plus a bunch of bolt ons, went with autolite iridium xp3923 plugs, i've heard some people telling me to keep them gapped at stock .032 and others telling me to gap them to .028 anyone have any solid advice?, thanks

autolite's american ford i belive so i'd start with a more german kinda plug and they should be pre gaped but when i got mine the guy gave me the wrong gap which happen to be the autolite iridums which was .028 for sure should already be there and if u did gap make sure you check them all for that little tip being gone even know it burns off to like a .o50 when u get good and done with them anyways
