Best drop-in air filter panel?
Hi.
I had a service last month, and my garage fitted a Bosche S9051 drop-in air filter.
Any good? Any difference if I change to something else?

As above will only work when car is mapped as with a thinner filter allows more air than a slightly restricted one.
So yes they will benefit, most fit upgraded one without a Tweek and expect it to work but all it may do is make idle a bit funny.
I did same with my Audi when going to stage 1 map.
