Reviews of OEM Volkswagen spark plug

I’ve had an APR stage 1 ECU tune on my 2017 GTI since 2020 with zero issues. I don’t track it. Just change plugs every 20k miles and have VW use OEM plugs.

I changed the spark plugs in my nieces 2.5L VW Jetta because it was idling at 1300rpm. Rock solid idle at 700rpm afterwards. Easy way to save some gas.

Changing the spark plugs, spark plug wires, ignition coil and the coolant temperature sensor fixed the cold start issue.

These are OEM plugs without the VW branding so cheaper, I run these in my stage 1 Mk7 GTi and they are good just need to gap them down quite a bit as out the box they are I think .32? I change them every 15,000km or every 2nd oil change

Hope you screwed them in with the correct torque, unlike my VW dealer. They started to unscrew themselves and causing instant misfire and rpm drops to 200 and engine shutoff.

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

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.

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.

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.
