Advance Headers High-Performance Mild Steel Exhaust Extractors for Ford 4.1L 250ci Crossflow Inline-6 Engines
The Advance Headers Performance Exhaust Extractors (A492) are precision-engineered for the legendary Ford 4.1-Litre (250 cubic inch) Crossflow inline 6-cylinder engine family. Built as a highly versatile multi-application header assembly, this kit fits both classic cast iron and later-generation aluminum alloy cylinder head configurations. Covering iconic vehicles from classic Falcon passenger cars (XC to XF series) and heavy-duty Transit commercial vans, to full-sized F-Series trucks and Bronco 4WDs, this heavy-duty tubular manifold upgrade dramatically drops backpressure to optimize exhaust scavenging velocity and unlock real torque.
PRODUCT CONTENTS:
- 1 x Heavy-Duty Mild Steel Performance Exhaust Extractor Header Set (Left & Right Assembly Path)
Key Features:
- Universal cylinder head mounting footprint is precision-engineered to match perfectly with both early iron-cast and modern lightweight alloy Crossflow head designs
- Tuned mandrel-bent primary piping pathways ensure completely uniform gas flow routing, eliminating the severe restrictions and localized heat traps inherent to factory cast iron logs
- Substantially optimizes low-to-mid range torque delivery and pulling power—critical for heavy commercial towing, outback cruising, and classic muscle car acceleration
- Heavy-duty mild steel construction structurally built to handle severe inline-6 thermal load transitions and demanding operational heat cycles safely
- Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against warping and high-pressure exhaust gas leaks

⚠️ Crucial EGR Emissions Fitment Note:
Please be advised that if you are installing this extractor assembly onto Ford Falcon XF models running active factory emissions management, you will require a specialized EGR Adapter (Part No. A492AD) to safely reconnect and secure your factory emission plumbing lines to the headers cleanly. Please confirm your vehicle's emissions setup prior to purchasing.
Please Note: Professional installation by an exhaust specialist or qualified classic automotive mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
