Spark plug Denso or AC DELCO

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 :)

Over the years I’ve found that the factory recommended spark plugs typically work best. There are exceptions, but my ‘95 5.7 recently got some plain Jane ACDelco plugs and it is running great.

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 just put in regular AC Delco plugs and it runs great.

My 2010 came with denso, replaced them with ngk at 100k, then at 200k replaced them with denso…not sure if it made a difference

my truck uses denso and NGK dual electrode plugs and will run very poorly if u try to use anything else

Bought a set of iridium plugs that were wasted after 15k miles. Amazon gave zero fucks. AC Delco gave zero fucks. The scum bags who sold them changed their name and keep selling.
