Spark plug Bosch or Denso

I just got Bosch ones for my 2gr in the Lexus. Worked well, no complaints. And they weren’t badly priced

The plugs EQT recommends are compatible. I’ve been running Denso 5749 plugs for over 10k without issue

I believe BOSCH were the OEM for the spark plugs on these. I went with Copper/Nickel plugs the the originals were Platinum, again I believe, I'm not 100 percent on that. I'm using a shortened maintenance schedule because I use the car for Auto and Rallycross so I'm ok with changing the plugs a bit more often.

I’m working on my 08 GTI FSI and man she loves my paycheck like no tomorrow! But she is the greatest car I’ve ever owned. Congrats you’re going to both hate and love it!!! Check the coil packs! Mine use to misfire all the time. Brought it to three shops before I personally replaced all four and bought nothing but NGK or Bosch plugs.

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.

I'm still not entirely convinced that it is weak or under ignition versus over fueling. Either way it just seems like it's having a hard time burning the fuel that it is getting. I still can't help but wonder about the Bosch Platinum 2s. I have had good luck with them before my Mark 2 GTI and the car did run well with them for a good 10 days before all of this started.

I went with OE ignition coils and bosch spark plugs and the misfire went away for a couple days but came back on my drive to school.

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

Bosch spark plugs are also trash.

Those spark plugs are junk, and on top of that, they are now carbon fouled. I would strongly encourage you to install new, normal, spark plugs.
