Best Spark plug for Volkswagen Passat

I went to colder plugs from ngk and noticed a difference in shift pattern for the better (my car is an auto).

2015 Passat 1.8L TSI 170,00 miles. De-carboned the combustion chambers and cleaned the spark plugs. Resolved slow response to accelerate. No oil consumption after 3k miles so far.

I had a 2012 Passat I drove for 10 years (after buying used with ~20K miles) and only just replaced two weeks ago with ~125k miles. I had to replace the alternator at one point and some other general stuff like spark plugs over the years, but that was it really. Nothing super expensive.

Got some NGK Ruthenium HX plugs at NAPA this morning. Miss is gone, car runs perfectly again. Plus they're cheaper and supposedly will last longer than the platinums.

I went ahead and replaced all 4 coil packs and plugs as well as the PCV valve. Since I have to order parts, it seemed faster than checking the plugs and swapping coil packs, as well as good insurance, since the coil packs and PCV valve were (over)due for replacement anyway. It took about an hour without rushing. Took about a 30-minute test drive, highway and town, and the engine's running smoothly. Ran a scan when I got home, and no new fault codes, so I cleared them all out and the check engine light went out.

I have used NKG FOR THE PAST 6 years on the car , no issues at all. Recently replaced them with Bosch OEM spark plugs , it’s same shit , no difference.

Just swapped out some pretty old looking OEM bosch plugs that were gapped at .045 for some reason. Put in PFR6Q at .032\". Didnt notice much of a change.

the plugs are brand new Bosch Double Platinum.... so then I went out, put them back in and was still a biotch to start....

I put in NGK PFR7S8EG plugs and man the car ran like absolute CRAP when it was cold. It ran fine, even great when it warmed up but it was so bad when cold that it was virtually un-driveable especially under moderate or hard throttle. I ended up putting the old plugs (Bosch platinum/iridium) back in because it was so bad.
