4.6l trickflow plenum

  • Sponsors (?)


I like mine, except it whistles. Sounds sort of like blowing over the top of an open coke bottle. Did your C&L whistle?

I got mine last summer, when the price was $143. Wish I would have waited for the current $99 price - the best plenum value out there.

:cheers:

Best plenum value on the net! I actually got an even knock-off-e-er one on ebay a few months ago, only $70 bucks shipped :p Exact casting of a C&L, just no logos, then I port/polished and gasket matched.

You have a leak somewhere.

I thought I had eliminated any chance of a leak, and that the design of the plenum itself caused the whistle. I'll triple check it. :cheers:

I tefloned the threads of all the fittings that go into it, and snugged them down tight. I'm still using the stock tb. The gaskets seemed fine. I guess the source of a leak would be tb to plenum or plenum to manifold.

I put a little bead of RTV between my plenum and TB...just to be sure.
