What pipe to use for air intake?

This is a very basic question, I know, but I can't seem to find the answer anywhere.

I need to redo the air intake (not exhaust) for my high efficiency boiler.

• Is the air intake pipe regular white PVC that you can get walking into a home depot, etc?
  
• Or is it a special material and size that you need to get from some HVAC supply?
  
• If it's something special what is it called?
  
• Also just regular PVC glue or something special?
  

The only thing I can find when I look up intake pipes is the concentric intake exhaust which I don't have.

Thanks
