Spark plug Denso or OEM Subaru

I bought a box of denso.

Everyone has been praising (fleet vehicles).

Im with the Densos already and the spool and throttle response is so much better. Even with gap 0.075mm they are much better.

I have the denso ikh24 and no problems for me.

ive ran the denso plugs in my stage 2 gli, and they worked great, had no issues with them.

Denso IKH24 plugs gapped to 0.024". 6,900 miles. APR Stage 2 tune. Only issue was CEL error when we installed the Unitronic downpipe and flashed to the stage 2 tune. After troubleshooting and contacting APR, they had my shop re-flash to a stage 2 beta file, no more CEL error.

IS38 APR tune with Denso IKH24 plugs, no brainer cheap insurance.

I did swap in Denso IKH24 at APR recommendation. Runs nice and have no issues to share

Had these on my MKV and they made the car smoother too.

Currently just swapped to Denso's IK20 like 2 months ago. They run pretty good. But now its mid summer over here and the car runs a little bit underpowered at those high temps.

At this point it's only showing symptoms after idling for 30 seconds or more (and even then not every time), like while waiting at a stop light. Only in first gear, second and beyond have no hesitation. This evening I swapped out the almost new Denso plugs (correct gap) and the problem seems absent.
