Pacemaker Headers PH4001 – Ford Falcon AU XR8 TE50 5.0L EFI Windsor V8

Pacemaker PH4001 headers (extractors) are engineered for Ford Falcon AU XR8 and TE50 models fitted with the 5.0L EFI Windsor V8. Their interference design and mandrel-bent pipework help improve exhaust gas flow and scavenging compared with restrictive factory exhaust manifolds.

Featuring 42mm primary pipes, 48mm secondary pipes and 57mm flanged outlets, PH4001 headers are designed to increase usable low-to-mid range torque, sharpen throttle response and improve overall engine breathing and performance. They are an excellent upgrade for street performance vehicles, restorations and weekend cruisers.

Why Good Headers & Exhaust Systems Matter

• At 5,000 rpm, the 5.0L 302 Windsor V8 draws in approximately 10,000 litres of intake air per minute and expels around 30,000 litres of exhaust gas per minute at approximately 600°C.

Warranty & Compliance

• Backed by Pacemaker's 2-year manufacturer warranty
• Warranty applies according to Pacemaker's current manufacturer terms and conditions
• Verify emissions and registration compliance in your state.
• Installation should provide adequate clearance from wiring, hoses and other heat-sensitive components.

Frequently Asked Questions

What vehicles do PH4001 headers suit?
Pacemaker PH4001 headers are designed for Ford Falcon AU XR8 and TE50 models fitted with the 5.0L EFI Windsor V8.

What size are the PH4001 header pipes?
PH4001 headers use 42mm primary pipes, 48mm secondary pipes and 57mm flanged outlets.

What is an interference design header?
An interference header uses the timing and arrangement of exhaust pulses from different cylinders to assist exhaust gas scavenging. The design is intended to improve usable torque and throttle response across the street-driving rev range.

Are header gaskets included?
The cylinder-head-to-header gaskets are not included unless specifically selected or stated otherwise. The recommended gasket for this application is DSF003A.

Are high-flow catalytic converters available?
Yes. Matching high-flow catalytic converters are available separately. Contact us for the correct components for your vehicle and exhaust configuration.

Can these headers be ceramic coated?
Yes. Ceramic coating is available separately under product code PHC10 for improved heat management, appearance and corrosion resistance.

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