its only an 8v GTI so not running more then 120-130 horses lol,they defo aint been in there for 20k miles (i think just over 20k), il get some good 1's from bizzle.he said his got some NGK's tripple electrodes grade 7? that mean anything?he said that grade 7 run better then grade 6 as once the car gets hot the grade 6 plugs dont fire enough and can cause premature detination & grade 7 run at high temps and you will feel the power even when the car is hot.i will buy these from him and report back to see if there is any diffrence in power when the car is hot.thanks people for all your help.
