New E89 With N52 Maintenance

[dryadsdad]

I’m a new owner of a 2011 E89 with the N52 engine. I’m approaching 40k miles so figure I must be up for a maintenance routine. I went online finding suggested maintenance schedule from a third party source. It said that at 40k I need oil change, cabin filter change and new sparkplugs. I can see the oil change and cabin filter but it seems low miles for new sparkplugs.

So my question is if I do need new plugs at 40k or if it can wait until 50k? Second, is the replacement of sparkplugs on an N52 a simple plug change or does it demand new coils as well?

Any further comments welcome. TIA

I have N52 2.5 engine. I do 5k oil changes, plugs might reach 50, i replaced at 40k, pretty much tips burnt off. Rear shocks were duff at 45k. 2 year brake fluid, done 5 year anti freeze. Replaced coils at 80k but old were fine, just precaution.
Gearbox oil at 50k manual box.

Thanks. Based on the Carfax, the maintenance has been kept up so I plan on keeping it that way. I'll ask that the plugs be replaced after all. AFAIK, the suspension is all right. I'll get the gearbox oil too at 50k. I too have the manual.
