Spark plug OEM Toyota or Denso

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.

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).

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

Those look great last time I did mine they were all carboned up but I was at 300k but definitely made a difference in Fuel economy and a little less sluggish

I’ve owned my truck for a year now and just decided to take out the spark plugs to see how old they were… mfs were the original factory plugs 14 years old and ran for 246k miles.. basically got a brand new truck now haha

Back in March two days after finishing the Water Pump replacement it started misfiring. I started with replacing the spark plugs with OEM Denso's, but that didn't fix it but was VERY NECESSARY.

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.
