Might find your alloys are heavier than the wheels that were on there, when you've been driving with nice wheels for a while and go back to harriers it suddenly feels like a pig. Also, what brand of filter did you use? Having swapped between a few myself, i'd say it's worth buying genuine, you might find it's restricting fuel flow, which will in turn lean out combustion and delay turbo spool.
