Any good brands I should be looking for when buying new glow plugs? Even if you dont have diesel bimmer may be in your other cars, you can recommend? I know for example NGK irridium spark plugs have great reputation for petrol cars, may be something is similar for diesels?

well, glow plugs are only used to help start the engine on very cold days. They don't function like spark plugs, and are not required for combustion once the engine is running. I wouldn't really worry about spending much more for a "good brand".
