I've treated my daily, an 04 3.0 petrol X5 to an inspection 2 service, inc new filters and spark plugs.
Feels quite different... more power.
Is it a placebo effect, or can new plugs and bits make a difference?
I've always imagined that as long as a plug was sparking OK, then a spark was a spark on the basis all it had to do was ignite the fuel mix.
