Spark plug BRISK or OEM Volkswagen

I changed all sparkplugs now my vw is running great. make it's the correct sparkplugs.

I just did mine not too long ago, replaced with Brisk ER12S. Didn’t need a coil puller tool, just had to be careful getting them out. Warming up the engine is helpful too. Otherwise an easy job.

And also removed and cleaned my spark plugs. All these collectively seemed to have a great impact on the engine\u2019s performance! The engine runs much smoother and feels a lot more sporty!

Ive been using the Brisk USA Premium Racing Spark Plug 14mm... yeah I get it they are kinda expensive when it comes to spark plugs at little over 13 dollars a piece but trust me they are worth it, ive never had good luck with any of the spark plugs listed for the 2.5l, specially not with what I've done to it, iridium plugs, platinum, copper, Nicole, even ruthenium plugs.... but these Brisk plugs are killers, ive never had my car run this well before, even my throttle response is better and the heat range is correct as well..

New plugs and coils went in and the misfire is gone. Sounds healthy too.

I got mine from ECS: drop-in replacement and no issues even with my Burger unit on map 2.

I currently run the Brisk er12s and have been happy with them...I'm mpi running full e85 and the car responds well. It's also what my tuner recommended.

would suggest plugs, RS7 or Brisk 12's (cheaper) but coil packs are not needed.

I'm getting some knocks in all cylinders in the first revision, more than I did with the Cobb OTS map and stock spark plugs. Hopefully it gets sorted out in the next couple of revisions and if not, I'll have to check the spark plug gaps or maybe re-run with the Cobb OTS and see if the knocks are due to the tune or spark plugs.

Overall, the power delivery is great.

I have the same problem with my recently acquired 2011 Sharan. Tried a suggestion of new spark plugs with no success.
