Spark plug NGK or OEM Volkswagen

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

OEM plugs are NGK as well.

I changed my plugs recently and qent with NGK Ruthenium gaped a step colder and they are working well for me, seem better than Motorcraft but thats just my opinion.

I just did the 30k service and my mechanic recommended these plugs. They are expensive, but worth it.

Learned 40 years ago to use NGK. Installed brand new Autolite plugs in my girlfriends Grand Prix and it ran like crap. Went to a speed shop and they sold me a set of NGK. Ran perfectly. Have only bought NGK or Denso since.

I used these in my '19 with no issues.

spark plugs every 30K with NGK IKR9J8(Iridium plugs better than stock also used on high HP builds). I don't care that the manufacturer suggests longer intervals but i know my engine is healthy and runs almost like new.

They run just fine on stock setup. Changed mine 6 months ago once the car was at 30k miles and actually managed to snap one of the plugs in the head ???? Carefully managed to get it out though. No noticeable difference from factory plugs.

I just came across a recent problem while doing my spark plugs at 80,000 miles. The dealership was the one that did my spark plugs at 40,000 miles. Sure enough, they broke Cylinder 3\u2019s wiring harness connector to the coil pack and stripped the bolt. I had to helicoil the bolt, replace the connector, and repin the connector.

Additionally I would endorse the use of a Champion or NGK plug. The LG/Torch/random Chinese plugs are a crap shoot. I see tons of failures on them as well.
