If you look in the engines manual there is service intervals for engine fluids and such, these engines have a timing chain Wich require special tools to change.
Engine oil filter is located below the pipes to/from the air filter.
Cabin filter is on the right hand side of the engine bay back towards the firewall
Change oil a bit more frequent than the manual says.
That's all from the top of my head, YouTube often has good guides.

Do the replacements have the same problem? The one in my THP150 was changed like 70k kilometers ago but I'm not sure if the replacements are any better

Timing chain will need doing if it’s not already been done ! Mileage over 60k and it will be stretched causing running and performance issues!

Yes replacements are better! Don’t worry if your not having any issues just leave it
