Best Spark plug for Volkswagen Golf

Stage 2 EQT E85 and NGK 91006 here, but I only order from NGK directly.

Brisks are great plugs. Do be warned however, their groundstraps are softer than others and open gap much sooner vs other plugs. So you'll be checking them much more often and changing them sooner than the usual 10-15k tuned interval.

I went to Brisk ER12S a few weeks after going 1+ tune which are one heat range colder, same fitment as MK7.

You can honestly just run stock plugs on the 1.8 with OTS tuning for stage 1/IS20/38. I ran these same VW/NGK "RS7" plugs including track use for thousands of trouble free miles.

Check out getting rs3 spark plugs if it’ll work.

I use Denso IK20TT and these spark plugs work every time, on both fuels.

So the new set of plugs arrived, so switched out them along with new wires, since two broke during work (Magneti Marelli) and since I already tested and bought a new coil pack basically the whole ignition system's now revamped.

So far after more than two hours of driving, no problems, but Im really careful since I dont wan to find out Im wrong, but it feels ok.

The old plugs where NGK, and after pulling them, their resistance measured on average about 4 kohms.

I kept the previous set, which where Beru's and they measured ~1.4 kohms.

The new set is Bosch, and Im going to stay away from NGKs since I drive a little bit sporty, lasted less than two years, and (I think) 20'000 km.

This. I had the 7s in previously. I swapped to the 8s when someone mentioned they got better fuel mileage with them I didn't notice any difference.

after putting the new ones i changed all the spark plugs too, to fit them properly with new wires. but the car runned roughly, so bad..and when mechanic unscrew the new spark plugs to see, they were carbonized black, with just a ride around.

I’ve heard bad things from mechanics about Bosch, specifically Bosch platinum.
