I've been toying with doing this for a while and as I'm about to install an S3 intercooler into the Tig I'll have the front end off.

So my question is in relation to the lower grille which has half of it blocked off (see pic below). The top section is blanked off whereas the lower section is open. Just wondering about removing the top "blanking" and having air flow through the whole lower grille. Is there any issues with doing this? Plus side is better cooling but wondering if it's going to cause me any issues.
