What is the reason for the ripples in the air brige coupler? -- Is it only for ease of assembly (adjustment for misalgnment), or did GM purposely incorporate it into their design to purposely create turbulence which does not seem to make any sense?-- I would think that smooth uninterupted air flow would make more HP? Maybe at 405 HP it is unimportant, but the more we modify to increase power then maybe it then becomes an issue requiring a aftermarket "smooth" style coupler???

 

The 'ripples' are for flexibility.

You can buy cheap aftermarket flexible rubber/silicone hoses to replace it.

Where do we buy these cheap hoses?

The ripples makes it easier to install & remove. On some car the ripples allow the engine to rock without breaking the connection.

 

After 8 years this, simple part would have changed if there was any benifit in adding HP. The new 7 liter Zo6 500 Hp engine is using this same type coupler.

I just think the smooth ones look nicer.....and you can choose colors as well.

 

Might pick up 1 horsepower if you are lucky
