E39 520i power loss after warming up solved!
Yesterday I’ve changed the camshaft sensor and sparkplugs.
I bought the OEM Bosch sparkplugs that this car had and all I can say now is WOW!!
The car had the original sparkplugs and coils and still working since 1998, but the sparkplugs were a bit loose and compression was escaping as you can see in the picture above.
Long story short, it feels like a new car and I’m happy 😊

PS: That is extra ground for coil-pack because I know there are some issues with this chapter on 6 cil engines on BMW, so a ground wire 8mm thick should solve the problem.
24h after the changes/mod.
Fuel consumption was reduced by ~30%.
It’s very nive to cruise on highway with 6-6.5l/100km and with 10l/100km in the city.
