I'm doing a full PI swap for my 98 GT soon and i was wondering what the best Plenum is...thanks for your input!!!
Don't get C&L , I got one and it whistle like mofo. I am getting sick of it but at first was cool cause it's sound like supercharger/turbo
Probably the cheapest one you can find. They all flow nearly the same amount of air so it is hard to justify spending $200+ on an Accufab when a $100 Prof. Products plenum will give you maybe 2-3 hp less. That being said, I would buy the TrickFlow plenum. It is like $99 from www.SummitRacing.com.

My C&L is totally quiet, its paired with a frpp 70mm tb. I have had it on 2 different
GT,s love it . I would say something else is making the whistle.
I have the C&L, my husband has the TrickFlow. Both perform the same function. If you look inside of the plenums to compare the inlets look the same as well as the curve inside the plenums. My C&L makes absolutely no noise at all.
lvmustanggt: I would check the gasket that is located between the intake, and the plenum. It sounds like you have a leak somewhere, maybe a vacume leak
You should check the IAC connection and the hose right next to that is a vacuum. Both should be snug. Is your throttle body tightened all the way to the plenum? Next to check would be your air intake and all the parts accociated with that. Last thing that could be making noisein that area is the emissions crap on the right side of the plenum.
