ur a good man -
for changing em early.
felt a difference after changing mine.
night and day.
omg -
how did they look after 23K -
i know mine look like chit.
the dealer keep giving me the wrong plugs - n54 ones.
finally told them to use my VIN.
btw, how do u like ur Cobb tune over the Dinan.
is ur throttle response past 3k in 2nd and 3rd feel any different.
lot more dramatic in the mid range i'm guessing.
