Which spark plugs

I have a 2012 GTI SE, stock with around 85k mi. I'm thinking about changing the spark plugs. Which ones do I want? Platinum? Double platinum? Iridium?

I pulled out out to look at it, and it's branded NGK VW. ECS has OEM plugs, but they're Bosch, not NGK.

ECS has the NGK Iridium plugs for $31, Platinum for $50, and Bosch OEM for $75.

Thanks!

Please don't give them that much money for spark plugs. I run these on my Stage 2 GTI with no problems.

i paid 128 bucks for my kit with spark plugs and R8 Coil packs. They went up a little.

Use the forum code : GOLFMK6FORUM
That takes off $7 so its 132.99

Same here and they are great. However, if you aren't tuned I'm not sure they are necessary. I believe these are a step colder than stock? Also, gapped to .028 and not .032.

I changed two sets of plugs on our 2.0T in our Tiguan and helped several friends with theirs. In every case the coating on the plugs, be it platinum or iridium was always still good, the breakdown happens with the internal resistance of the plugs increasing and becoming too high.

IMO Get the cheapest plugs you can, cos even the expensive ones don't last long.

Here's the recommendation I received from HS Tuning

- IF you are using water/meth injection, you might consider using the BKR7EIX, as the iridium plugs are more resilient to erosion from exposure to methanol.

- IF you live in an exceptionally hot climate and don't have an upgraded intercooler, you might consider using the NGK PFR8S8EG. It's exactly the same as the stock plug, just one heat range colder.
