Manifold~ help!

[polowoof]

Hi every one,
I have seen this supersprint manifold from a 16v GTi 1.4 mk3 in the ebay
http://cgi.ebay.co.uk/VW-Polo-MK3-Super ... 286.c0.m14
I was wondering would this fit my polo 1.4 8v mk3?
If so how much would it be? more importantly would this make anydifference on the performance ? now i only hv K &N induction kit and Earth cable
Later may put an exhuast with the backdrum would this tgt with the manifold helps?
I jus started off mod on my polo and need some adive~
