As I am new to BMW ownership was wondering what the spark plug life is ?
The plugs in mine were changed 10,000 miles ago so when will they be next due assuming the right ones were fitted on the last but one service ?
The handbook does not list spark plug options.
Looking for advice as to which ones to use. In the past I have used long life plugs so cost is not really an issue just want to fit the best ones for the 325i engine.
