Hi there,

I have just bought and installed an HKS air filter kit for my series 7. Upon removing the standard airbox i realized that there are six hoses attached the the box. The intake manifold on the HKS filters only have an extra port on each which means i can only attach 2 of the hoses to the manifold, the other two being the actual filters themselves. Now there are two hoses that go no where.

The car runs fine but now the boost gauge wont read and i suspect its something to do with the stranded hoses? Can anyone tell me why and where these hoses are suppose to go, and what to do with them?

Any help will be much appreciated.

Cheers, Andy
