Spark plug Denso or OEM Audi
Spark plugs are simple too, just need the proper sockets and swivels. Took me about 45 minutes. That middle plug on passenger side is the toughest, but twisting boot 180 degrees and pulling it out from the front made it a breeze!
Pros: simple, easy to install
Cons: middle plug toughest
If you doing the spark plugs do the coils too. For the spark plugs use Denso 3499 (about 15 dollars each), for the coils use Denso 673-1310, (about 50 dollars each).

The plugs EQT recommends are compatible. I’ve been running Denso 5749 plugs for over 10k without issue
Pros: compatible, no issues

Part number: 5749
i just put the densos in my '17 alltrack with a stage 1 tune and they run noticeably smoother than stock. i gapped them to 0.026" before install. it didn't seem like plugs would be that important for a stage 1 tune so i've been surprised.
Pros: runs noticeably smoother
Vehicle:
Volkswagen
Denso always.
Pros: good quality
Vehicle:
Toyota
They look good but if the vehicle has 83k, they were replaced before, Denso is OE on toyota and Autolite are shit plugs so no way they were in since the car was brand new.
Pros: look good
Cons: shit plugs

Toyota

my truck uses denso and NGK dual electrode plugs and will run very poorly if u try to use anything else
Pros: dual electrode plugs
Cons: runs very poorly
Yes! I had a set of iridium spark plugs bought off Amazon that were counterfeit! They were denso but I didn’t discover it till about 40k miles later when I had a misfire. Pulled plugs and they were toast… first set lasted 120k and looked fine..
Cons: plugs were toast, misfire
Mileage: 64373 km
