start with getting yourself some 10w 330 ohm resistors (at least 2) and cut the N112's off and place them there. Then remove the black metal tray of the N249 which you no longer need if you're not using the cover.
Then replace all vac lines with blue 4mm and try and keep em as much out of sight as possible.
that there shouldn't cost more than an hour work (Max!!) and about 10 quid.
Then you can get an open airfilter, and remove the big ugly airbox you have now.
it will look something like this: (but here is still has the N112's)
then you can change all the black hoses for blue 1 by 1.
You could also sand and polish your inlet, chargepipe and rocker cover, which doesn't really cost much except a lot of time!
