Spark plug Bosch or OEM Volkswagen

Oil change at 123k miles \ufffd\" OEM filter and Castrol Edge 5w40 OEM air filter at 116k miles OEM cabin filter at 116k miles OEM Bosch spark plugs at 116k miles

My plugs seem to still be running great, only have about 35,000 kms on them.

I did replace the spark plugs at 70k miles

Bosch components made in the EU (this is the important part) are in many cases the items that VW installed on the car in the plant, or better. Take the spark plugs for example, Bosch just prints the VW name on it and VW installs it in the engine.

I have just replaced the oil and all 6 spark plugs with Bosch Double iridium.

Just changed out the original plugs in my 2014 Ed30 GLi at 58K and totally agree with the other observations here. The idling has improved tremendously and the general over all performance of the car is back where it should be.

But otherwise, Bosch FLR8LDCU+.

Lesson learned: DO NOT EVER EVER EVER USE BOSCH PLATINUM (STANDARD TIP) SPARK PLUGS IN YOUR VR6 ENGINE.... THEY JUST DON'T WORK!

If you use anything but OEM plugs in a stock white block, well just don't do that. Also Bosch Platinum, great for having to pull your head and find out what the center of the plug did to your engine

For the OEM Bosch plugs, I would check them every 10k-15k miles at a minimum, based on what my stock plugs looked like @ 19k miles (sh!t).
