Spark plug Autolite or Denso

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 used them in my 2007 Tacoma with no problems. Left them in for several years.

I put autolite's in my 2010 V6 and they've been perfectly fine.

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

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.

My dad just returned a set of autolites. I installed them and had immediate misfire.

Once we got a good local supplier for Motorcraft plugs a few years ago we almost never install Autolite.

There seems to have been quality issues with those for quite a while. I couldn't count how many times we removed fairly new Autolite spark plugs and replaced them with a better brand to fix a misfire.
