PVC fitting
 

I've heard that some plenums make use of the larger sized PVC fitting located on the driver's side front corner of the plenum, pre-2001 vehicles may have smaller PVC hookup and therefore an adapter may be required. My I know my car is a 2001 but an early model 2001 so was wondering if this applies to me? Or do most plenums out on the market take care of this?

Most take care of what you are talking about, they include both sizes. And its PCV you are referring to.

Thats what I thought......

When i ordered mines, they sent me the wrong one, instead of returning it, i got a hose to adapt it and some small clamps and called it a day. :D
