I like NGK, but you can't go wrong using what the manual calls for.
Champion and NGK have good reputations.
Ngk’s are hard to beat.
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 bought these when I did my last tune up and plug swap just to try. I noticed zero difference in power or mpg.
Damn $40/plug, I have a nissan altima 2012 and got the most expensive one at $30CAD/plug NGK iridium laser and it was out of necessity as cheaper ones was out of stock during lockdown.
