Construction

Advance A692 headers feature heavy-duty press-bent construction and an interference design developed for street performance applications.

The design is intended to provide strong usable torque through the normal road-going engine speed range while reducing the restriction of the original exhaust manifold.

Please contact Best Mufflers for advice on compatible catalytic converters, exhaust systems and installation components for your Falcon 3.9L or 4.0L six-cylinder.

Vehicle Fitment

• Make: Ford
• Model: Falcon
• Series: EA / EB / ED / EF / EL / AU
• Performance Models: Applicable XR6 models
• Year Range: 1988-2002
• Engine: 3.9L SOHC inline six-cylinder petrol

The A692 application covers the Australian Ford overhead-cam six-cylinder Falcon family from the EA introduced in 1988 through to the final AU-series Falcon in 2002.

Engine Note: Early EA and EB models were available with the 3.9L SOHC six-cylinder. The engine family subsequently developed into the 4.0L SOHC six used through ED, EF, EL and AU, including performance versions used in applicable XR6 models.

• Brand: Advance Headers
• Design: Interference design
• Construction: Heavy duty
• Pipe Forming: Press bent
• Engine: 3.9L / 4.0L SOHC inline six-cylinder

Fitment Notes

A692 is designed for the Ford 3.9L and 4.0L SOHC overhead-cam six-cylinder engine family. It is not an application for the earlier XF-style pushrod Crossflow six-cylinder engine or the later BA-onwards DOHC Barra engine.

Current Advance application information also lists the corresponding XG and XH Longreach 4.0L commercial models. If ordering for an XG or XH ute or van, please provide the vehicle details so fitment can be confirmed.

Because many EA-AU Falcons have now been modified, confirm the engine, transmission and existing exhaust configuration before ordering.

What's Included

• 1 x Advance A692 header assembly
• Bolts
• Gaskets

Recommended With

A suitable high-flow catalytic converter and performance exhaust system can further reduce downstream exhaust restriction. Contact Best Mufflers for advice on the correct exhaust combination for your Falcon and intended use.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 3.9L Ford six-cylinder theoretically draws approximately 7,800 litres of intake air per minute at 100% volumetric efficiency. Using an illustrative hot exhaust volume at approximately 600°C, this represents around 23,400 litres of exhaust gas per minute.

At the same engine speed, the 4.0L Ford six-cylinder theoretically draws approximately 8,000 litres of intake air per minute, representing around 24,000 litres of hot exhaust gas per minute using the same illustrative calculation.

A well-designed header and exhaust system helps manage this high gas flow efficiently, reducing restriction and improving exhaust scavenging, torque, throttle response and engine performance.

Installation Tips

Professional installation is recommended. Check header clearance around the steering, transmission, starter motor, engine mounts and surrounding components before completing installation.

Lubricate threaded fasteners with WD-40 or a similar penetrating lubricant before removal to assist with easier removal and installation. After installation and several heat cycles, inspect the system for exhaust leaks and recheck accessible fasteners where appropriate.

Warranty & Compliance

Installation should retain all emissions-control equipment required for the particular vehicle and comply with applicable Australian state or territory requirements relating to exhaust noise, emissions and vehicle modifications.

FAQ

Is this product currently available?
Availability and lead times can vary. Please check availability and current lead time before ordering.

What Falcon models do Advance A692 headers suit?
A692 is designed for selected Ford Falcon EA, EB, ED, EF, EL and AU models fitted with the 3.9L or 4.0L SOHC six-cylinder engine.

Do A692 headers suit the XR6?
Yes. A692 is suitable for applicable XR6 models within the EA-AU overhead-cam six-cylinder family. Please provide your model and year when ordering if you are unsure.

Does A692 suit both the 3.9L and 4.0L engines?
Yes. Advance lists A692 for the 3.9L and 4.0L SOHC inline six-cylinder Falcon engine family.

Does A692 suit the Ford Falcon XG or XH ute?
Current Advance application information includes XG and XH Longreach models with the 4.0L SOHC six-cylinder engine. Please confirm your vehicle details before ordering.

Does A692 suit a BA Falcon?
No. The BA uses the later DOHC Barra six-cylinder engine and requires a different header application.

Are these headers mandrel bent?
No. This A692 product is specified as press bent. Do not confuse it with the current stainless-steel A692SS version, which has different construction specifications.

Are bolts and gaskets included?
Yes. The supplied A692 product information specifies that bolts and gaskets are included.

Can I pick up from the store?
Yes. Pick up is available but must be pre-arranged before collection.
