viewtopic.php?f=98&t=21828V6 Only, the I4 is a different box.
Some things I have noticed:
Con:
- There has been some discussion about reduced fuel economy when using the V6 boxes (I put mine right when winter fuel was coming out, so I can't tell with any certainty if this is true)
- I received a message from GDE stating that their tune is specifically tuned for our standard box. While the V6 wouldn't show too many losses, it would show some.
- '04+ require extra plugs to fill holes (<'03 don't have the holes)
Pro:
- V6 box reduces water vapor from being sucked in through the grill opening, and by design better prevents water from damaging your filter.
- Easy mod to switch back and forth (~5min and a screwdriver), so you can swap the box when you are headed to the trail, and back to your stock box for commuter duty. This also forces you check your filter more often... which is never bad!
