Spark plug BRISK or BERU
I've been using beru rs7 plugs without any issues.
Pros: no issues
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.
Pros: easy job
Cons: be careful getting them out
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..
Pros: killers, car runs well, better throttle response, correct heat range
Cons: expensive
Vehicle:
Volkswagen
I got mine from ECS: drop-in replacement and no issues even with my Burger unit on map 2.
Pros: drop-in replacement, no issues
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.
Pros: car responds well
Mileage: 5000 km
I got a set of APR coils and Brisk Silver Racing ER12s plugs for around 200
Vehicle:
Volkswagen
Part number: ER12S
Yup, these are great. Just be sure you gap them to APR's recommended gap of 0.024" ±0.002" or 0.6mm ±0.05mm. If you want 1 step colder plugs, not needed on your setup, but if you do for the future in Stage 2+. For 10$ more than the OEM NGK you can get the BERU.
Pros: great, step colder plugs
would suggest plugs, RS7 or Brisk 12's (cheaper) but coil packs are not needed.
Pros: cheaper alternative
Cons: tighter plug gap
Vehicle:
Volkswagen
I swapped out the oem plugs for Beru rs7 plugs when I went APR stage 2 at ~3k miles. The car ran well. Fast forward to the present with over 18k miles and is20 swap, and I noticed a few stumbles at idle. Nothing major but I figured I'd change them since APR recommends 10-15k mile intervals (visually the Beru plugs looked fine).
Pros: car ran well
Cons: stumbles at idle
Mileage: 18000 km
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.
Pros: great power delivery
Cons: getting some knocks
