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.
I run 0.024 but I’m running Brisk plugs in my car on a custom tune. They’re pre-gapped to 0.026 and anywhere between those two would work fine for my specific plugs.
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.
But otherwise, Bosch FLR8LDCU+.
i changed the original NGK spark plug with new Bosch super 4 spark plugs. a nice improvement but still far from old good performance.
iv had mor problems with a brand new bosh plug then any other plug.. even cheap knock off checker brands...
Every time I fill up I check my mileage, I could never get great MPG from the FR8DS, but the coppers were way better MPG wise. Throttle response was less as well. The Silbers always looked more sooty during inspections than the coppers. The silver plug will last longer.
