get a grip ipap the name of the front bumper black plastic bottom bit has several different names i.e spoiler, splitter, trim and i'm sure a hell of alot of other names no one is picking hairs and who cares what it's called it might be cosmetic but i can assure you i didnt do it because it increased the mpg or bhp or anything else for that matter as far as i'm concerned it looks better than the original
and the makers and suppliers called it a VW Golf Mk3 GTI VR6 Front Lower Deep Euro Lip Spoiler
oh and don't be offended just getting down from my work buzz lol
