You can honestly just run stock plugs on the 1.8 with OTS tuning for stage 1/IS20/38. I ran these same VW/NGK "RS7" plugs including track use for thousands of trouble free miles.
I forgot to mention that I installed brand new pre-gapped NGK spark plugs two years ago
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.
I bought these when I did my last tune up and plug swap just to try. I noticed zero difference in power or mpg.
I just changed out my sparks and found out the previous owners put these garbage plugs in it lol replaced with quality Iridium NGKs
I did buy 3 set ngk iridium from ebay for several vehicles and they are all fake . it misfire and destroy coil too...as soon as took the out the tip of the plugs worn out to the bone...
