Z1 Silicone Recirculation (or Blow Off Valve) Outlet Hose.  All 1990+ 300ZX Twin Turbo Models came with two of these rubber hoses.  These hoses are different for right and left side applications.  This silicone replacement hose connects the outlet side of the stock recirculation valve or aftermarket blow off valve to steel intake plumbing.

These hoses not only look nice they are far easier to work with than your old hardened stock hoses.  If you are planning on replacing your recirc hoses or recircing aftermarket BOVs, you will love these easy to work with hoses. 

4 ply reinforced high quality silicone hose, custom formed for perfect fitment on the Z32.

Z1 Motorsports offers a full line of silicone hoses for the Z32 that will be the last hoses you will ever have to purchase.  They will outlast the car at less cost than OEM replacements!  There's no reason to consider anything else. 

This kit is for both hoses.
