Spark plug Champion or Denso

Champions quiet redesign of their plugs to match Tempest made up my mind. It matters, and Champion is just trying to save face.

I have eqt and the densos and they are smooth

Denso IKh024

I run the Denso.

Denso 5749 non projected

I got some good tips from the community and went with Denso IKH24. Also bought a gap tool to properly gap them. Im planning on swapping them out every 8k.

Almost everyone either runs the HKS plugs or Denso plugs. I personally have had no issues running the Denso plugs.

For what it's worth, I've changed my plugs twice (OEM to Denso to Beru-RS7) and never noticed any oil or any difference in color between the plugs.

Im running denso step 2 cold plugs from bms website and tbh i regret not going with the hks plugs

I got some phony Denso marked spark plugs
