Spark plug Denso or OEM Audi

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 :)

Some weekend progress after work, got the plugs changed out and fresh air filters are in.

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.

ive been using the RS7 spark plugs(Gapped properly) and swap every 10k miles, but nowadays I do not run very hard, just cruise and occasional hard accelerations. Paired with APR coil packs, havent had any issues.

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.

Denso or ngk. Bosch at worst. I would recommend against the off brand in your photo.

I tried Denso once. I took Denso’s out and replaced them with Denso’s. They ran for 500 miles and quit.

Im running denso step 2 cold plugs from bms website and tbh i regret not going with the hks plugs
