I recently purchased one of the smooth Couplers to replace the accordian type stock air coupler. It is so stiff, I couldn't get it on the throttle body or the air bridge.
This coupler looks like a big piece of radiator hose and it is tappered
Does anyone have any tips? I tried putting a little dab of soap on it to make it slide better, but it almost seems it is to small.
I would suggest soaking it in a pan of hot water for a few minutes, to soften it up. Then, maybe just rub a little motor oil on the ends, to allow it to slip over the connections.
You can put your hand inside the coupler to start it on the throttle body, and then use two small (pocket) screwdrivers to gently start it on the air duct.
Good luck!
I wonder what you have. If it looks like a radiator hose I would consider returning it.
What I would use is a silicone coupler, not rubber. The outside surface should be shiney with about a 1/8" wall thkns. It should swage down about mid-length to match the outside diam of the TB.
Eklers, Mid America and lots of other suppliers carry them, about $50.
i got one of them it fit pretty easy just a bit if twisting and what not i donno if it dose much but ohh well i use it to hold me intake in place (aftermarket) lol
Not to start a coupler bashing but, is it for cosmetics or is there performance gain? If performance gain, then why is the new Z06 still have the ribbed style. Seems the Z06 could have boasted with more HP.

GM probably just stuck to the good old reliable accordion merely for the reason that it's something they know won't fail. They put a new part on, and who knows.
I've read there's a small performance gain with the coupler. It's also nice having a new part to install.
These couplers (siliconeintakes) wont work if you are using the stock airbridge. The TB is 4" as is the MAF but the stock airbridge is a oval shape, aprox. 4" x 4.75" ??? at least at the TB side as I remember. The 4" to 3.75" coupler works with after market airbridges like the carbon fiber power duct by BPP.
