2004-2008 Acura TSX Exhaust Manifold OEM JDM K24A

OEM Acura TSX Exhaust Manifold (2004–2008)

Looking for a replacement Acura TSX exhaust manifold? This genuine OEM JDM exhaust manifold is engineered specifically for 2004-2008 Acura TSX models equipped with the 2.4L K24A DOHC i-VTEC engine. Salvaged directly from low-mileage Japanese import donor vehicles, this factory manifold delivers exact factory fitment, balanced exhaust flow, and proven heat tolerance that cheap aftermarket headers simply cannot replicate.

Whether you are repairing a cracked factory runner, restoring a daily driver, or completing a custom K-series engine swap, choosing an authentic Acura TSX exhaust manifold ensures seamless installation with factory downpipes, oxygen sensors, and heat shields.

Vehicle Compatibility & Fitment

This factory exhaust manifold is designed for direct bolt-on installation on the following applications:

• Make & Model: Acura TSX (CL9 chassis)
• Model Years: 2004, 2005, 2006, 2007, 2008
• Engine Configuration: 2.4L K24A2 (USDM) / K24A (JDM) DOHC i-VTEC 4-Cylinder
• Transmission Compatibility: Compatible with both 6-speed manual and 5-speed automatic transmissions
• Interchange Note: Also widely used for custom Honda Civic and Integra K-swap configurations requiring OEM clearance.

Why Choose Genuine OEM Over Aftermarket Headers?

Aftermarket tubular headers often suffer from thin gauge metal, poor weld penetration, and recurring flange warpage caused by repeated thermal expansion cycles. Installing a genuine Acura TSX exhaust manifold eliminates these common failure points:

• Cast & Formed Durability: Built using heavy-duty factory alloys designed to handle high exhaust gas temperatures without cracking.
• Precision Mating Flanges: True, flat cylinder head and catalytic converter flange surfaces prevent annoying exhaust leaks and blown manifold gaskets.
• Preserved Sensor Bung Placement: Factory O2 sensor bungs remain in their engineered locations to prevent check engine lights (CEL) and maintain accurate air-fuel ratio readings.
• Direct OE Replacement: No custom bending, cutting, or fabrication needed—bolts directly to standard exhaust piping.

Part Condition & Multi-Point Inspection

At Dominance Inc., all recycled parts undergo a detailed visual and mechanical inspection before entering our inventory. Every Acura TSX exhaust manifold is checked for:

1. Structural integrity across all four primary exhaust runners.
2. Absence of hairline cracks around collector joints and heat shield mounting bungs.
3. Flat, clean mating surfaces free of deep gouging or excessive corrosion.
4. Intact threaded sensor and bracket mounting holes.

Note: As a used OEM Japanese import part, minor cosmetic surface oxidation or road grime may be present, but mechanical functionality is fully preserved. New exhaust gaskets and mounting hardware are strongly recommended during installation.
