In one of the last couple of issues of 5.0 Mustang they tested the latest dual plenum BBK intake against an Edelebrock performer, a GT-40, and a Trick Flow Street. If I remember correctly the GT-40 was within about 3 horsepower of the best ones on the market. I believe the Cobra flows right with a GT-40, so why would you change? For only the chance to pick up maybe 5 horsepower is it worth it?
It blew me away that such a supposedly hightech intake was only a few hp better than the old GT-40.

It was designed really well. The test was against a bbk ssi intake, edelbrock performer, and I think it made the best lowend and midrange hp and tq, while only being down a few hp on top. It was a mild street combo, and different intakes might have done better with a different combo,(more aggressive cam, ect..). The combo had a comp cam, afr 165's, full length headers, ect.. Might be better to port to get those few extra hp, but you could get a different intake if you want, or are going to get a more agressive combo. I believe the gt-40 and cobra have the same lower, different uppers, and flow #'s are close, I think.
If you want a dyno example of how a well ported Explorer killed an RPMII - go to my website and read the "why port an intake" article.
