Afternoon, 
I am wanting to replace my spark plugs on GTI (AXX) stage 1 (r-tech)
going with standard plugs,  from what i have found on here thats the better option. 
My question is this, do i go Bosch(can't find the ref for the bosch plugs) or NGK (06H 905 611)?
Have you guys found that a particular plug works best? 
Can anyone pass on the bosch plugs ref?
I will also be replacing the coil pack.  

Any help would be much appreciated. 
Happy new year
