Replace a cracked, warped, or leaking upper intake manifold with a genuine OEM unit pulled from a Chrysler 3.5L V6 donor vehicle — restoring proper airflow and a sealed vacuum system to your Charger, 300, or Magnum.

This upper intake manifold (plenum) was engineered specifically for the Chrysler 3.5L SOHC V6 used across the 2007–2010 Dodge Charger, Chrysler 300, and 2007–2008 Dodge Magnum. It retains the factory plenum shape, throttle body mounting flange, EGR and MAP sensor bosses, and coolant crossover ports in their original positions, so it bolts up using stock hardware and connector locations without modification.

Product Highlights

• Genuine Chrysler/Mopar OEM upper intake manifold (plenum)
• OEM part number 4591863AJ
• For 3.5L V6 SOHC engines only — not for 2.7L V6 or 5.7L HEMI V8
• Molded composite housing with factory mounting flange and sensor bosses
• Upper intake plenum only — throttle body, lower intake, gaskets, and sensors are not included unless shown in photos
• Direct replacement for compatible 2007–2010 Dodge Charger, Chrysler 300, and 2007–2008 Dodge Magnum models
• Exact item pictured will be shipped

Vehicle Fitment

• 2007–2010 Chrysler 300 (Base, Limited, S, Touring, Signature Series) — 3.5L V6
• 2007–2010 Dodge Charger (SE, SXT) — 3.5L V6
• 2007–2008 Dodge Magnum (SE, SXT Wagon) — 3.5L V6

This manifold does not fit 2.7L V6 or 5.7L HEMI V8-equipped Chargers, 300s, or Magnums, and does not fit Magnum model years outside 2007–2008 (Magnum production ended in 2008). Confirm your engine is the 3.5L V6 before ordering.

What Is Included

• Upper intake manifold (plenum), as pictured

Only the components visible in the photos are included. Throttle body, lower intake manifold, gaskets, and sensors are not included unless they appear in the photos.

Condition

Pre-owned genuine OEM part. May show normal cosmetic wear from age, road use, and previous installation. Please review the photos closely, including:

• Plastic housing — check for cracks, warping, or heat damage
• Throttle body mounting flange and gasket surface
• EGR and MAP sensor bosses
• Coolant crossover ports
• Mounting bolt holes and hardware

You will receive the exact upper intake manifold shown in the photos, not a stock photo or substitute unit.

Verify Fitment Before Ordering

This platform was built with more than one intake manifold configuration across engine sizes. Before ordering, compare:

• OEM part number — 4591863AJ — against your original manifold
• Engine size (3.5L V6 only — not 2.7L V6 or 5.7L HEMI V8)
• Mounting bolt pattern and flange shape
• Sensor connector locations and shapes

For additional fitment support, send us your VIN and a clear photo of your original upper intake manifold or its part number before ordering.

Why Choose a Genuine OEM Chrysler Upper Intake Manifold?

• Correct plenum shape and volume for proper airflow and factory idle quality
• Sensor bosses and ports in the exact factory locations — no adapter fittings
• Proper gasket sealing surface, reducing the risk of a repeat vacuum leak
• More straightforward installation than a generic aftermarket manifold

We have one of these in stock. Once it's sold, sourcing another OEM upper intake manifold for this platform isn't guaranteed.

Installation

Professional installation is recommended. Removing the upper intake manifold on this engine involves disconnecting the throttle body, EGR tube, MAP/IAT sensors, and several vacuum lines — and on this platform, the cylinder 3 spark plug sits underneath this manifold, so budget extra labor time for that access.

A rough idle, a lean code (P0171/P0174), or a vacuum-leak whistle can also be caused by a failed intake gasket, a vacuum line, the PCV valve, an EGR tube seal, or the purge solenoid rather than the manifold itself. Confirm the upper intake manifold — not just its gasket — is the actual source of your issue before ordering.

Order With Confidence

Purchase from Right Choice Auto Parts for accurately represented OEM automotive parts and responsive fitment support. We have one of these in stock, and once it's sold another may not be available. Confirm your engine and VIN, then secure this OEM upper intake manifold while it's here.
