Spark plug NGK or OEM BMW

I have Seat Leon FR 2.0 TFSi 2007 DSG F1 165k KM, stock engine, and stock map, only things I've done since I purchased it were: spark plugs NGK

I just changed the plugs in the wife’s e46 or should say that’s what was in the wife’s vehicle ngk whatever model they were.

Rockauto has the plugs(NGK 97181)

If you’re tuned on stock turbos, OEM or NGK 97968s.

Im tuned and on an E85 mix but using 1 step colder NGK's (#ILZKBR7B8DG) gapped to about 0.022...needed these before I even went MHD though. Once I did most of my maintenance, the car required this for proper spark. Night and day of a difference.

I had similar problems with mine until I tried stock F80 M3 plugs. Mfg #12120039634KT1. Mine was 07 N54 FBO.

I still put a small dab even though the NGK plugs recommend against it. I change my plugs every 15-20k because I have a tuned Focus ST. I already went through 3 sets of NGKs with no problems doing the small dab

I've had multiple Chevy engines that gave random misfire codes with autolite plugs- then ran fine on ngk.

Replaced spark plugs on a 2009 Corolla 1.8L. I used NGK plugs, should I swap out to Denso?

Now that I've done the job, I can't tell if it's just in my head but the car seems to have less power now. It was already a sluggish engine to begin with it but it feels like I need to floor it even more. Also, the gas mileage has dropped from 25 MPG to 22.5 MPG.
