I think IIRC you were also planning on getting an exhaust , so If it were me yeah I would go with the filter.
air in air out .
yes the influx of air should need some jetting changes
My opinion is based on a few bikes I owned form around that time piped filter and jet kit made a huge difference.
those who did it half assed (most my friends lol) usually ended up with a bike that ran like shit.
