I have no clue if an 01+ would get the same results. I'll have to let someone who actually knows engine tuning answer this question. If anything, be a guinea pig and do what he did: buy it, try it, post results!
Here's the intake design on 97-00 SOHC's....air comes in the TB, splits in two on the sides, then enters into a lower manifold with individual runners....
