This year I will be upgrading the turbo, intercooler and all the other stuff. My question is, as I have a smoothed front bumper

I don't see the point of running a huge radiator that people run with a wide mouth, I was thinking of one of these, as the main air feed will be through the small grill at the bottom

Will this be sufficient? I think it will be fine.

Absolutely not, you might as well just keep the SMIC rather than fit such a small FMIC.

Don't agree anything is an improvement over the factory smic as there useless, have you ever logged a mapped tdi on intake temps ? It's not good at all

I run this tx autosport kit on mine and logged before and after it does it job perfectly halfed my I take temps and stays low aswell
