Advance Headers | Mild Steel Exhaust Extractors | Ford Falcon Fairlane BA-BF 5.4L 3V V8 | A63

PRODUCT CONTENTS:

• 1 x Heavy-Duty Mild Steel Left-Hand 5.4L 3V Extractor Header Assembly
• 1 x Heavy-Duty Mild Steel Right-Hand 5.4L 3V Extractor Header Assembly

Key Features:

• Engineered specifically to seamlessly integrate with BA-BF generation engine bay footprints, factory oxygen sensors, steering shafts, and starter motor configurations
• Tuned mandrel-bent primary piping pathways ensure completely uniform internal flow geometry, optimizing gas velocity past the wide constraints of the modular overhead-cam V8 cylinder heads
• Substantially optimizes low-to-mid range torque delivery—ideal for improving throttle crispness, everyday driving responsiveness, and heavy towing capabilities
• Heavy-duty mild steel construction structurally built to handle intense engine bay thermal expansion cycles and typical high-torque V8 operational vibrations safely
• Thick, precision laser-cut cylinder head flanges maintain a flat, ultra-stable mating footprint to permanently guard against face distortion, thermal warping, and high-pressure gas leaks

⚠️ Crucial Engine Variant & Valve Architecture Alignment Warnings:
1. Strictly 3-Valve V8 Models Only: This product (Part No. A63) is designed and space-mapped exclusively for the 5.4L 3-Valve SOHC engine footprint. Because the exhaust port configurations, bolt layouts, and deck profiles differ substantially, these headers will NOT fit 4-Valve DOHC V8 engines (such as Boss 260, 290, or 315 variants found in XR8 and FPV models).
2. Chassis Packaging Fit: Formed precisely to navigate past the factory steering rack linkages and tight passenger-side starter limits unique to BA and BF generation sedans, wagons, and utilities. Retains full integration with factory O2 feedback sensors, though minor downstream pipe alignment checks are required during assembly.

Please Note: Due to the tight physical constraints of the wide modular V8 engine inside the BA-BF engine bay and the estimated 4-hour technical fitment frame, professional installation by an exhaust specialist or qualified automotive technician is highly recommended.
