I use only NGK or Beru spark plugs.
use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.
Pros: correct heat range
Cons: wrong heat range
Had these Beru plugs put in last year. Are they the kind that’s at greater risk for damaging the engine?
Cons: risk for damaging engine
Part number: 06K905601M
I've been using beru rs7 plugs without any issues.
Pros: no issues
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
I ran Beru RS7 plus which are one step colder when I tuned stage 1 and they didn't last at all. Might have been under 10,000 miles. Recently went with NGK plus that APR reccomends for stage 2 and so far so good. No misfires since.
Pros: no misfires
Cons: didn't last
Mileage: 10000 km
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 have the beru side firing and they work just fine.
Pros: work just fine
I've had much success with BERU plugs on all of my VW's, especially my 16V's. Beru maks the stock/replacement plugs for Porsche, VW and Audi (I work at a Porsche dealership, I see it all the time)
Pros: success with BERU plugs
Vehicle:
Volkswagen
