Yet Another Spark Plug Thread

[seeyainakia]

So she has been acting funny last couple weeks, with last couple days very bad (My Stinger, not my wife, this time), and I figured I should check the plugs. These are Denso plugs gapped at .022 as per BMS with barely 20,000 miles. Probably closer to 18-19K. When I tried to check the gap the remaining center electrode just disintegrated and some of them were pushed out to .045. In the picture I attached the side electrode looks oily and dark but it's actually not, just an effect of the picture.
Anyway, I swapped them out for the HKS M45iL and will update this thread in hopefully more than 20,000miles or whenever i have to swap them out.

These denso plugs seem to be causing a lot of problems with stingers.

I lost an HKS M45XL plug after only 20k miles, I can live with that, but IDK if that is normal- threw a 1304 code with CEL In my 2022 2.5T. Moved the coil pack to cyl .1, has not come back in the last 3 weeks.
