**Edit** car is S3 2012.
Right, after 17k of stage 2 running I think I'm in need of spark plugs.
At idle it's not ticking over as smoothly as I'd like.
Now I've searched, been in Warrens thread and a few others.
OEM is best I've read, but what exactly are we calling OEM these days?
"NGK BKR7EIX" ?
"NGK PRF758EG" ?
Bosch have been mentioned?
Or which is best for Stage 2 tuned car?
