Spark plug NGK or Denso

The plugs EQT recommends are compatible. I’ve been running Denso 5749 plugs for over 10k without issue

I buy the OEM ngks every time. I find cars CAN be picky about what plugs you get.

I picked up a set of new VW Atlas sparkplugs of FB MKTplace locally for a good price and before I tossed them in one of my cars I decided to verify all of the spark plug differences and to reserve the research here are my results:

I have mentioned numerous times here to remove Torch plugs and replace. One would not run fresh out of the box (WEN). Replaced it with an NGK and it's been purring ever since.

If I had a choice between a resistor type NGK plug and a non-resistor Torch, I'd take the NGK in a heartbeat.

i just put the densos in my '17 alltrack with a stage 1 tune and they run noticeably smoother than stock. i gapped them to 0.026" before install. it didn't seem like plugs would be that important for a stage 1 tune so i've been surprised.

I already replaced the spark plugs with the Denso ones I listed though... Is this bad?

Had some Denso plugs in my '15 WRX (unaware to me) and the plug in cylinder 2 was fouled within 7k miles and caused a misfire. Turns out the shop that the previous owner took it to for the 60k-mile plug change decided to cheap out. I now have OEM plugs :D

Careful with Denso, back in MK7 days some complained that the plugs would shatter and cause engine damage.
