Had a busy Sunday, oil flush and change done with new set of spark plugs.
I Installed NGK 97506 gaped at 0.020.
I must say that I am quite surprised how much difference a new set of plugs made, car seems to burble a lot more and the idle and drive is super smooth. I will definitely be using the same plugs on the 535i which currently has the NGK 95770, curious to see if there is any difference to how they perform :smilebounce:
Old yucky oil filter. Age: 15k km Looks like I might need to drop my service interval to 10k km.
Just to add, the old plugs were worn out evenly and did not throw any errors. :cartel:
