eBay Bicooler Hose Spacer

The eBay bicoolers that use the CSK hoses sometimes have an issue where the branch of the hose that goes to the stock location intercooler is too large in diameter to snugly fit onto the IC inlet/outlet pipes.

The following are steps I’ve taken to address the issue.  Here’s a picture of the stock GTI inlet and a spacer sleeve that I created using a piece of silicone hose that has been trimmed in length.

The inlet and outlet outside diameter is ~60 mm.

A short piece of silicone hose with an equivalent inside diameter is trimmed to the correct length and placed over the end of the inlet.

Now the branch of the ebay (CSK) IC hose will fit snugly over the inlet pipe.

For clamping the hose in place I prefer to use a clamp that is narrow enough to to be seated in the center of the area.  The thought being that with the sleeve also installed I wanted the force from the clamp to be far enough behind the bead to keep the hose and sleeve from being able to slide off the inlet.

    1. Possibly. So far the one time I have had a boost hose come loose was elsewhere, this has been working for me. The hose is unlikely to blow off, it would more likely be the clamp being forced off toward the side of the stock location IC. This branch of the IC hose can’t be removed unless one of the other ends has been removed first, trying to push this branch off the IC will put more tension on the hose, so the further it is pushed away the more tension there is. If this ever becomes a problem I’d expect the hose clamp to slide off but the hoses to remain place. Been using it for a while now and it hasn’t happened.
