  Description:

  Genuine OEM Nissan Left Exhaust Manifold with Integrated Catalytic Converter — Part # 140F2-EZ30A

  Replace your cracked, failed, or emissions-failing left exhaust manifold with the factory-correct assembly for Nissan's 5.6L VK56VD engine. This genuine OEM assembly is the complete left-bank (driver side) exhaust manifold with the front catalytic converter integrated directly into the manifold — a single unit that replaces both the manifold and the pre-cat in one assembly. Built to exact factory specifications for correct port alignment, correct catalyst efficiency, and long-term durability.

  Part Details:

  • Part Number: 140F2-EZ30A
  • Other Names: Manifold Assembly-Exhaust LH W/Catalyst, Exhaust Manifold with Catalytic Converter, Mnfd W/Converter, Catalytic Converter With Integrated Exhaust Manifold
  • Condition: New, Genuine OEM Nissan
  • Position: Left (Driver Side)
  • Application: 5.6L VK56VD V8 engine — Standard Titan and Armada
  • ✅ Includes Front Catalytic Converter (integrated)

  ⚠️ Critical Fitment Notes — Read Before Ordering:

  • Fits 2016–2020 Nissan Titan (standard) from 07/2016 — to 12/2019 production
  • Fits 2017–2020 Nissan Armada
  • Does NOT fit the Titan XD — different manifold configuration
  • Does NOT fit 2021+ Titan or Armada — updated manifold assembly required
  • Always confirm your exact model, production date, and engine with your VIN before ordering

  Compatible Vehicles:

  • 2016–2020 Nissan Titan (5.6L VK56VD — standard, not XD — from 07/2016 to 12/2019)
  • 2017–2020 Nissan Armada (5.6L VK56VD)

  Always confirm fitment using your VIN and production date before purchasing.

  Why buy OEM? Aftermarket exhaust manifolds with integrated catalytic converters frequently use inferior catalyst substrate, incorrect port geometry, and lower-grade cast iron that cracks under the extreme thermal cycling of a 5.6L V8. The genuine Nissan assembly is the only manifold built and validated to the VK56VD's exact port velocity, back pressure, and catalyst light-off specifications — ensuring correct emissions compliance and long-term engine performance.

  Symptoms this part fixes:

  • Exhaust leak from the left bank manifold — ticking or hissing at the head
  • Failed emissions test — pre-cat catalyst efficiency below threshold
  • Check engine light with catalyst efficiency codes (P0420) — left bank
  • Cracked or broken manifold visible on inspection
  • Exhaust smell from the engine bay or inside the cabin
