Default intake coupler replacement

the intake coupler that runs to my tb is torn at the flange..i was thinking about replacing with the power coupler that corvette central sells..is anyone else running those or is going back w/ ribbed coupler better?

Default Turbulent Question

I don't think it really matters much I run the "old school" OEM one - I mean how much turbulence could it create?
Check the cost of each - if there close get the power coupler thingy and you can add one more item to you mods list.

I've seen some posts here about using a rubber plumbing connector for hose between the TB and MAF. If memory serves you should be able to find out the specifics on what one to buy by doing a search on "home depot" in C4 tech.

The stock coupler is of an "accordian" style so that it is more flexible.
It is connecting a rigid, stationary part (the air filter housing, which is bolted solidly to the chassis) to a moving part (the engine, which can move on its mounts).
There is a reason the flexibility is desired and, if the smooth coupler gives no benefit...and it doesn't, other than mod list addition...then why would it be a good choice?

Feel free to put the smooth coupler in the same catagory as the airfoil, the TB bypass, the throttle advancer, and the temp sender relocater.

I've got the "power couplers" on my 95, just for the look. If you want the stock ones send me a PM.

a 4" to 3" rubber reducer from home depot's PVC pipe section fits perfectly on the early C4's

I have my TB-->rubber reducer-->MAF-->Filter stuck directly on MAF.

All I can add to this thread is that's it's easier'n shet to cut your fingers while installing/removing those darned things. Those screw clamps that hold the coupler in place have some seriously sharp edges to 'em!

i think on the lt1 you can get the tb to the maf, but not the maf to the air filter. i looked at them at home depot.
