For the 2007 IS250, do we have a two stage intake system? What does that mean anyways?

 

If you mean does it have ACIS, yes, all of them do. It was introduced in 2006.

 

so what's the benefits of it?

It effectively changes the lengths of the intake runners depending on throttle input and RPM. Short intake runners is for low-end torque and it'll switch over to smooth & long intake runners for the high RPM ranges.

 

You might want to restate that - here's how Lexus says it works:

 

Does the 96 sc300 have runners would it help to remove them I use to have a honda prelude and I removed them from it..
