The OEM Left Front Hose 11823-40P01 has been discontinued by Nissan and is no longer available.  An alternative to this OEM 300ZX (Z32) Twin Turbo PCV System Kit is available from Z1 in silicone.

When rebuilding a engine or just doing routine maintanence the PCV system is regularly overlooked. The hoses tend to get hard and brittle causing leaks. The pcv valves get clogged and won't allow the crankcase to breath properly.

Kit Includes:

• 1 - LH PCV HOSE
• 1 - RH PCV HOSE
• 1 - LH Front Crankcase Ventilation Hose
• 1 - RH Front Crankcase Ventilation Hose
• 1 - PCV Hose on the back of LH head
• 2 - PCV Valves

Fits:

• 1990-1996 Nissan 300ZX (Z32) 
  • Twin Turbo models only

If servicing your 300ZX, a boost leak tester is highly recommended for your tool box and can make finding pesky air leaks much easier.
