I genuinely am intersted in answers to these questions because there is so much mis-information out there it's hard to tell what's what, or at least I'm not sure?

Thanks in advance.
Yes, the plastic you have to cut is not visible from the front of the car, but it still may affect resale value as potential buyer may look for signs of modifications.

Some intercooler flow better than others. I am not about to start a big debate here. What you want to look for is the least amount of pressure drop across the core and the highest drop in IAT's to start off.
