Has anyone put these on their 2.0Tfsi or S3?

If so did you notice a difference in performance?
 
I'd doubt you would notice a performance gain unless you previous ones were badly worn. They come in to their own by not needing changed as often, they last 80K IIRC.
 
I put some in about a thousand miles ago mate and i think she feels a little more responsive now.

I'm going back to my tuner in a few weeks,so will see if i can get updated dyno figures at the same time.
 
l put a set in 4 weeks ago and felt a difference, OEM ones had been in 11000 miles. l bought of ebay, 4 for 30. Regal sell for around 60.
 
I have installed NKG Iridium IX 2 months ago after experiencing misfires at idle quite often. After first replacing the ignition coils the misfires disappeared for a couple of weeks (no idea why) but returned on another cylinder so I went for new spark plugs although the old ones had about 25000km. The results were instantaneous, misfires disappeared and the engine runs a lot smoother at idle ever since. It also seems a bit more responsive in midrevs.
