im not sure how much heat pvc can handle either... plus the difference in outside diameter vs inside diameter is very great compared to aluminum or composite... so you might not end up being able to fit the right size piping in there. i wouldnt use pvc

 

well where can i get some pre bent aluminum or composite

 

$$$ at a race shop.

 

If you REALLY want an intake, you can pick a decent one off ebay for < $100 if not <$60
