Spark plug Denso or OEM Volkswagen

These are OEM plugs without the VW branding so cheaper, I run these in my stage 1 Mk7 GTi and they are good just need to gap them down quite a bit as out the box they are I think .32? I change them every 15,000km or every 2nd oil change

I recently was having a misfire in cylinders 2/3, and new plugs and ignition coils cleared it up.

DENSO ZXE24HLR7 is also an excellent OE plug.

Denso 3289 is what I run.

398k on the clock, like 50k on these plugs, she runs clean and smooth.

Denso for my runner

Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that

Replace with OEM - Denso. And yeah, get them from rock auto. Anywhere else is way too expensive and eBay is most likely counterfeit garbage.

So i just ordered a pack of 4s (the left one is from Denso Japan) from a local distributor carrying Denso spark plugs and of the 4, 3 are made in China and 1 is made in Japan. Comparing them side by side, the China ones definitely look subpar to the naked eye.

definitely not ok, they are spent, also Denso>NgK any day of the week

The previous owner had installed some Denso IKH24's that looked..... disgusting. In fact, I have NO CLUE how the car ran as well as it did, as the tips from the Denso plugs were gone, and the gap was 0.055. The car still had a slight miss after I did the coils last month which prompted me to replace the plugs.
