I want to replace most of, if not all of, my stock, rubber couplers on my car with upgraded silicone couplers from Hose Techniques.

Could someone please let me know the size of the couplers circled below; they seem the same size, but I could be wrong.

Thank you.



and the y pipe coupler...

Intake couplers are 2.5". Intercooler couplers are 2.75". Just FYI, the coupler in that picture to the IC is a Hump Coupler (if you are trying to get one just like it).

Thank you!

What is the benefit of the "hump" coupler?

Hump couplers are there to help absorb movement from either side of the connection. i.e. if the IC is bolted to the frame and the engine is sitting on mounts which allow movement, then the engine can move independently of the IC. This could cause the coupler to eventually work itself loose. However, this doesn't happen as much and can also be mitigated by using constant tension (spring) clamps rather than t-clamps.

Does this include the ypipe coupler in the second pic?

I would assume yes, however I haven't had a stock y-pipe in 10 years.

Confirmed in a different thread. The ypipe coupler is 2.75.
