Spark plug Denso or AC DELCO

I've been running Denso (5346) IKH24 Iridium gapped .024 on APR stg1 for 48k miles and most recently on stg 2 with no issues.

41-156 is the new plug for the LE2 engine. Our 2016.5 got them, and they are fine. 41-123s came out of it.

Denso TT iridium are so far the best ones I’ve tried in terms of performance

if you want some good plugs, get some denso IKH24, they are 1 step cooler than stock plugs.. I change mine out every 20k miles..

IKH 24 plugs with stock coils work just fine. No cutout, rough idle or misfire.

Replaced stock with denso ihk24.

Plugs need to be AC Delco 41993 (no substitution). I've had misfires with other "equivalent" plugs that went away with the correct plugs.

So I went to my uncle who is a part owner of a auto parts supply company and he ordered me 5 Beck Arnley 178-8445 Direct Ignition Coils for my car and 5 ACDelco 41-806 Professional Platinum Spark plugs.

Just install my today, is it just me being paranoid or else? the engine noise sounds louder and it's very noticeable. Has anyone felt the same way? by changing out for these spark plugs, does it make any advantage performance wise? btw i am pretty sure the installation was good and not misfire or anything likes that. just more engine noise and not a good noise.

The original dealership where I bought the van installed Denso spark plugs part # SXU22HCR11S which were supposed to have a gap of 0.044 but they all had either 0.039 or 0.040. Apparently no one checked the gap before putting them in.
