I know how these are supposed to look, but they were very low.

Fair enough. I just wanted to make sure you were aware they're not like plugs in our fathers cars

But a change of plugs has really changed the way the motor responds.
Much quicker pickup of revs, and more bottom torque.
I do believe that when i change the fuel filter, it will again be almost as fresh as new.

This is just incredible, the car has a full service book. Always performed at BMW but even the oil filter was the original from new. date stamp was the same as production month. I could litterally see through the filter. Big holes everywhere.

The oil filter was original? Pics? How many miles?

Sounds like the filter hasn't been changed for awhile, but 10 years from date of production is a long time. I wouldn't take a numerical stamp off a filter as proof that the filter hasn't been changed. It could be date of manufacturing, or something else entirely.

As far as i could tell, yes it was the old filter.

I think the shop takes a Oil change litterally and only changes oil.
Have pics, will upload later.

Miles app. 150000

You had posted that the service book was stamped by the dealer. A BMW dealer oil service includes the oil filter.

I still don't believe that an original filter will run 150,000 miles. I have seen pictures of filters at 50,000 miles, just not at 150,000 miles and 10 years.

Could you post a graph with the dyno's wideband O2 plot?

Gaskets are good and not letting oil into the coil/spark plug area?

[Angeluz]

That's another issue i have to repair as well.
There is a small leak in to the coil area. which i will have to address soon.
by now it's only a small leak, which i could easily wipe off, but it has started, so i don't think it will be that long of a time before it gets really bad.

The plugs and coils were clean before the dyno test.
Will try to do a scan of the dyno report.
