Re: Neff Oven spares
MA hi
Both will fit your appliance.
The difference in the two is one is specifically manufacturer approved and therefore carries the price tag with it.
The other one is an quality tested alternative which has not been specifically approved by the manufacturer.
If your going to do this yourself, remember to be safe and only work on the appliance with it disconnected from the mains supply.
I hope this helps.
