Spark plug OEM Subaru 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.

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.

Changing my sparkplugs for the first time (32k miles, yes it's early but I got a great deal on the plugs) and found that the stock plug in cylinder 4 actually had a ground electrode defect and was significantly thicker than normal. The car runs stronger than it ever has as this was likely causing extra timing pull.

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

RIP doing spark plugs at home and not hating life.

Good luck doing spark plugs
