Z32 300ZX VG30DE/TT PCV Hose Set – Silicone

Often overlooked is the PCV System on the VGs. The PCV valves themselves are a recommended replacement item but PCV hose failure is another common cause of rough running and idling on your Z32s.

Nissan’s original rubber units turn hard & brittle with heat, age, contaminants & ultimately fail at some point. These PCV &  Idle Hoses(link to product) are a large contributor to running rich issues on your Z32 and often fail upon manifold removal & refitting. 

These are quality formed units specifically for TT or NAs & these will stay soft and never degrade in their lifetime.

*Kits come with replacement Spring Clamp Set to Silicone hoses

Replacing the actual PCV valves in the Upper manifold is a good way to ensure excess oil vapor stays out of your intake and ultimately contributes to better engine health & operation.
