This is what I got under my hood:
Its a Weapon-R secret intake. My filter is pretty much right in front of the blower fan. There are people here that has done custom pipping like jago. I would get an K&N filter cause its made of paper and it can catch dirt pretty easily than foam filters.

I think he got his from Autozone. Look up ebay for intakes. They sell a lot of them there. For the bypass valve, you can get them at your auto parts store or performance, but I don't have one as I'm still working on my engine bay.
