Recommended FMIC Size?

Hi guys,

Ive done a few searches looking at all the types of intercoolers that have been fitted to the mk1 vrs

From your experience what size would be ideal for a vrs.

I have the wide mouth bumper so I would like it to look proportional to the size of that but also have good performance within lag time etc.

The sizes I have came across so far are:~

550 x 225 x 64mm

600 x 300 x 76mm (too big I think)

450 x 227 x 65mm

Any help would be appreciated
