Spark plug OEM Audi or OEM Volkswagen

I just changed my plugs at 75,000 miles...I was impressed as to how clean the plugs were and the color. Looks good. The gap was still .030 as the new ones were (VW 06K905601K). Definitely could have gone much longer but it's an easy replacement.

I put a new battery in it. Because it needed one but then I changed the spark blood wires and it now acts like a brand new car, so go to your spark plugs first.

Some weekend progress after work, got the plugs changed out and fresh air filters are in.

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 been using the RS7 spark plugs(Gapped properly) and swap every 10k miles, but nowadays I do not run very hard, just cruise and occasional hard accelerations. Paired with APR coil packs, havent had any issues.

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).

120k miles on my 2015 a3 with a stage 1 tune. I did timing belt, tensioner, and water pump around 100k miles. Costed me like $1k. Also did spark plugs and a new battery, which was another $600.

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

I just came across a recent problem while doing my spark plugs at 80,000 miles. The dealership was the one that did my spark plugs at 40,000 miles. Sure enough, they broke Cylinder 3\u2019s wiring harness connector to the coil pack and stripped the bolt. I had to helicoil the bolt, replace the connector, and repin the connector.
