Used RB25DET NEO Upper Intake Plenum
Fits R34 Skyline / Stagea RS Four S / RB‑Swap Builds
Up for sale is a used OEM RB25 NEO upper intake plenum, perfect for anyone refreshing a factory NEO setup or piecing together an RB25DET swap. This is the correct NEO‑specific upper manifold with the revised runner design and improved airflow characteristics compared to earlier RB25 plenums.
Details & Condition:
• Genuine Nissan RB25DET NEO upper intake plenum
• Used, in good working condition
• No cracks, no broken mounting points, no welded repairs
• Threads are clean, flange surfaces solid
• Ideal for OEM+ builds, replacement of a damaged unit, or completing a NEO longblock
These NEO plenums are getting harder to find as more R34s and Stageas get parted or swapped, and they’re a must‑have if you’re keeping the factory manifold layout.
