OEM intake is by far the best option for stock and bpu engines, pop in a TRD or K&N panel filter and your good to go. I can't imagine that bit of silver foil is doing much to be honest, the cone will still be drawing nice hot air in from the sealed engine bay.
Regarding the ali radiator, again stock is known to be the best option for the car and many run the OEM rad with big BHP cars without any issue. I'm not saying it's bad but it sure won't be as good as stock.
The problem is people get far too hung up on form over function. When an OEM part needs replacing if they can do it cheaper and add a bit of bling in the process that tends to be the option they go for.
I'm not saying the car isn't worth a look You just need to let your head rule your heart and not the other way around as it could cost you more than you bargained for
