Spark plug BERU or OEM Volkswagen

I use only NGK or Beru spark plugs.

2015 Passat 1.8L TSI 170,00 miles. De-carboned the combustion chambers and cleaned the spark plugs. Resolved slow response to accelerate. No oil consumption after 3k miles so far.

Ive tried other plugs that are oem spec but not from VW and I like the way the oem plugs work better.

If you’re buying a used VW. This is the easiest one (Polo) to maintain.

1. Figure their parts change and maintenance schedules and follow. Check oil cap for oil type to use (15-20k is fine).

2. Always check oil hoses, rubber seals and gaskets (40-70k).

3. Change engine bushings (100k), chassis bushings (50k), transmission bushings (100k) for first time used buyer.

4. Check condition of all parts above before change, also include spark plugs. Stick to German OEM plugs (50k).

I replaced the spark plugs, ignition coil plugs, alternator and checked the tensioner.

use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.

FWIW, I just had spark plugs and coil packs done on my 2016 Jetta, $185 out the door at my local dealership

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).

I’ve done an oil change as well as swapping the spark plugs and coils for brand new ones. The roughness persists!

The factory spark plugs are honestly shit in terms of longevity.
