Spark plug Bosch or OEM Audi

Bosch should be the safest choice for German cars, but avoid their gimmicky "Plus 4" plugs that have 4 ground electrodes, unless that's what the car came with from the factory.

Bosch provides OE for VW spark plugs. Plug your vehicle into autozone and just buy the bosch ones. They come pregapped.

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.

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.

i changed the original NGK spark plug with new Bosch super 4 spark plugs. a nice improvement but still far from old good performance.

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).
