Spark plug Denso or Motorcraft

Eqt recommends NGK 4905 or Denso 5749. I personally run the densos and they have been good so far, they spark ????????‍♂️.

I'd opt for a set of 1 step colder plugs. Ideally non projected tip like [Denso 5749](https://www.fcpeuro.com/products/vw-spark-plug-denso-5749) or [NGK 4905](https://www.fcpeuro.com/products/vw-spark-plug-ngk-r74388). Though these are costly.

Hondas are notoriously picky about the plugs being Denso.

I’ve used denso IK20TT in whiteblocks and they work very well, may need to re gap if you have some boost raising shenanigans going on

I've never had any issues with Denso plugs, so I recommend those :)

Yes definitely get the original OEM Denso plugs and be really cautious of anything you purchase off Amazon a lot of them are counterfeits. You can either go direct to the Toyota dealer or you can go to your local parts store like Napa and just make sure you order the correct Denso Plug.

The plugs look really good pretty even color across all of them no major carbon buildup. Wear on the plug seems typical for 100,000 miles.

I've been running Denso IKH24 for 10k miles, have to swap them often but they've been great so far. Frequent changing will prevent damage to them seeing as they are normal projected grounds, but they are pretty cheap to replace once a year or so.

I heard from an old ford mechanic once that ford designed their ignition system around the motor craft plugs and no other brand plug will run right if installed. Since then only motorcraft or autolite in my fords.

I tried Denso once and didn't have great luck with them.

I tried one of the economy plugs on my 02 Accord. Ended up having to chuck it and buy a Denso.
