Advance Headers | Mild Steel Exhaust Extractors | Ford Cortina TE-TF 3.3L 4.1L Crossflow | A392

PRODUCT CONTENTS:

• 1 x Heavy-Duty Mild Steel 6-Cylinder Performance Crossflow Extractor Header Assembly

Key Features:

• Universal head face engineering guarantees a flush, completely reliable seal across early high-heat cast iron port layouts and subsequent lightweight alloy-head Crossflow block variations
• Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing exhaust gas scavenging velocity and preventing power-robbing pocket turbulence
• Substantially optimizes low-to-mid range torque bands—ideal for restoring throttle crispness, improving hill climbing capabilities, and cruise performance in street machines
• Heavy-duty mild steel construction structurally built to handle intense engine bay thermal expansion cycles and typical classic inline-6 harmonic vibrations safely
• Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, warping, and high-pressure gas leaks

⚠️ Crucial Engine Variant & Pre-Crossflow Alignment Warnings:
1. Strictly Crossflow Design: This product (Part No. A392) is shaped explicitly for Ford Crossflow engine architectures (where the intake and exhaust configurations sit on completely opposite sides of the cylinder head block). It will NOT fit early pre-Crossflow motors (found in TC-TD series Cortinas) where the intake and exhaust share the same side casing.
2. Chassis Packaging Fit: Formed precisely to navigate past the specific steering column splines, inner engine bay apron lips, and firewall wells unique to the TE and TF series Cortina bodies. It will not comfortably drop into alternative Falcon bays without secondary run checks.

Please Note: Professional installation by an exhaust specialist or classic automotive restoration technician is highly recommended to ensure perfect downstream pipe alignment and a solid gas-tight seal.
