Reviews of Denso spark plug

Swapped the NGKs (around 60k miles on them) for new OEM Denso plugs. That stopped the shaking for about two days, then it came back.

Spark plugs are simple too, just need the proper sockets and swivels. Took me about 45 minutes. That middle plug on passenger side is the toughest, but twisting boot 180 degrees and pulling it out from the front made it a breeze!

If you doing the spark plugs do the coils too. For the spark plugs use Denso 3499 (about 15 dollars each), for the coils use Denso 673-1310, (about 50 dollars each).

The previous owner had installed some Denso IKH24's that looked..... disgusting. In fact, I have NO CLUE how the car ran as well as it did, as the tips from the Denso plugs were gone, and the gap was 0.055. The car still had a slight miss after I did the coils last month which prompted me to replace the plugs.

Denso work quite well

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

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

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.

Denso always.

I also went with the IKBH20TTs. I noticed my mpg was better after doing so, and the truck seemed to idle and drive smoother.
