Factory is 52mm... For the extra money I would just get the 60mm, which may not help that much when ure NA, but if u plan goin turbo its a dream...

60 is a nice little increase when NA, but definatley a wet dream when boostin! but spend the dough and get the 60

the factory opening is 52mm but narrows down to about 46mm or so thanks to a massive hump right inside. 60mm makes ur car feel like a hotrod once you install it. i cant imaginie accelerating with the stocker after running the 60 for almost a year now. and yes, im still NA. the billet aluminum unit is nice as it looks fairly stock.
