So I was surfing the net to find a set of NGK plugs so I thought that given the 130i 128i 125i have the same engine I though that they had the same type of plugs too.
turns out that the 130i has a different part number than the 125i.
Now given that I have a tune giving the same output as a 130i (more or less) and having the same engine which type of plug shoud I get?
