What's up 4.6 guys...
I did a search first, and didn't come up with anything relevant. :bigthumbsup

I want to put a C&L Plenum on my car. I'm hesitant though because I read that the Professional Products plenum could cause fitment problems with the discharge tube on my supercharger and my strut tower brace. This was from a review of the Professional Products plenum on the American Muscle website, and could be speculation, but I think it's worthy of checking into before I order the part.

The Professional Products plenum looks to be about the same design as the C&L plenum (rounded on top) as opposed to flattened out like a stock unit or Accufab.

I know my strut tower brace was designed to work around CAI's and supercharger discharge tubes, but I don't know how an aftermarket plenum will affect the way everything fits under it. I have about 1/2 an inch of space currently between the top of the tube and the bottom of my strut brace, so if the C&L sits much higher, it ain't gonna fly.

Basically, I need to know if the C&L sits up higher on the intake manifold or if anyone has had a problem with this.

Well I had the PP plenum & throttle body with a strut tower brace. And let me tell you, it was a tight fit. I don't know how the supercharger tube routes up like if it sits higher or lower, but I wouldn't see why it wouldn't fit. I've read about loads of blown stangs with various plenums and they fit. It may be snug, but I'm sure it will fly.

It shouldn't make a huge difference in the location, I would think. It may still be a bit close, but nothing a BFH can't fix...... If it is too close, we could always notch it a little, and weld a plate in on the bottom side where you couldn't see it to strengthen it back up.

I can only speak about the PP plenum, and my intake is NA - but the biggest reason the PP plenum would not fit bolted in with the tower brace was the thicker base (for extra plenum volume) and it seems the stock plenum flange has a slight camber towards the valve cover. With these two variations my CAI tube would not clear the strut tower brace, the throttle body was higher and more towards the valve cover. But I agree with Bullitt, that right leg of the strut tower brace could be persuaded to make room. And if you can do some cutting and welding, well then the options are plentiful.
