Spark plug Denso or BERU

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.

I use [Denso IKH24's](https://www.fcpeuro.com/products/audi-vw-spark-plug-denso-ikh24). It's the projected tip version of the Denso plug EQT has recommended on their FAQ (IKH01-24).

I've been using beru rs7 plugs without any issues.

Use only Honda specified plugs (usually Denso Iridium) and they last 100,000 miles just fine.

I like ac delco. But I recently used denso tt fine wire plugs I two different ls engines. What a difference in power. And gas mileage.

I just replaced mine, at 80k, with Denso PLatinums. The same brand as the stock plugs.

Denso Iridium 1 step colder plugs. Running great on my 2017 Jetta 1.4T

No discernible difference to me, positive or negative. But since I am running APR stage 1, I followed APR's recommendation.

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.
