The EP-2690 is a Duraspark II electronic distributor for the Ford Fairmont and Fox body Mustang from 1978 through 1983. The Fox body platform (introduced with the 1979 Mustang) shared its engine and drivetrain with the Fairmont, and both used the Duraspark II ignition system -- Ford's mid-generation electronic ignition with both mechanical and vacuum advance, sitting between the earlier Duraspark I and the later EEC-IV/TFI system.

The Ford Fairmont and its Mustang/Zephyr/Capri siblings are an important bridge in Ford's product history -- representing the transition from classic muscle car platforms to the lighter, more fuel-efficient Fox body architecture that would carry the Mustang through to 2004. The Duraspark II distributor for this platform is also very widely used as a source of ignition hardware for enthusiasts upgrading older Ford vehicles from points to electronic ignition.

For the DSII swap all parts can be taken from a 1978/79 Ford Fairmont or Futura Distributor: A1 Cardone Part# 30-2690. The Cardone 30-2690 / A1C0/302690 reference and the O'Reilly part number A1C0/302690 make this one of the most recognized Duraspark II references in the classic Ford community.

HZPT is the international brand of Ningbo Xianlong Automobile Fittings Co., Ltd., established 1999. With over 25 years of automotive ignition distributor manufacturing experience, EP provides the aftermarket with reliable OEM-specification replacements for Ford vehicles across a 40-year production span -- from the 1958 Ford Club with its FE 390 V8 through the 1996 Econoline Super Duty with the 7.5L 460 big block.

EP ignition distributor production line

Every EP Ford distributor ships as a complete, plug-and-play assembly with cap and rotor included. TFI (Thick Film Ignition) module is included on EFI-era distributors where the original unit carries a distributor-mounted module. No additional ignition components are required for direct OEM replacement installation. EP is part of the Ever-Power Group, also producing bevel gears and a comprehensive range of mechanical transmission products.

Frequently asked questions

What are the symptoms of a failing Ford EFI distributor or TFI module?
The most common Ford EFI distributor failure is the TFI (Thick Film Ignition) module overheating and failing. Classic symptoms include: engine starts cold but stalls after reaching operating temperature, cools down and restarts, then stalls again -- the characteristic TFI heat-related failure pattern. Other symptoms include rough idle, loss of power at high RPM, intermittent no-start conditions, and a check engine code for the PIP (Profile Ignition Pickup) signal from the distributor. The distributor body itself can also wear -- shaft play, worn drive gear, or deteriorated seals allowing oil contamination of the internal components. When the TFI module fails, replacing the complete distributor assembly (including the new TFI module) is more reliable than replacing the TFI module alone on a worn distributor housing.
Does the EP-2690 ship with the TFI module, cap, and rotor?
Yes. The EP-2690 ships as a complete plug-and-play assembly. For EFI-era Ford distributors (1984 and later), the unit includes the distributor body, TFI (Thick Film Ignition) module, distributor cap, and rotor. For Duraspark-era distributors (1975-1983), the unit includes the distributor body, cap, and rotor with the magnetic pickup assembly. For classic-era FE distributors (pre-1975), the unit includes the distributor body, cap, and rotor. No additional ignition components are required for direct OEM replacement. The unit is ready to install after transfer of the vacuum advance hose and spark plug wires from the old distributor.
Why is the Ford Fairmont distributor so commonly recommended for Duraspark II upgrades on older Fords?
The 1978-1983 Ford Fairmont was produced in very high volume and uses a Duraspark II distributor in good supply at salvage yards and in the aftermarket. Its Duraspark II system (with the 4-pin external module and adjustable mechanical and vacuum advance) is mechanically compatible with a wide range of older Ford four-cylinder and six-cylinder engines as a points-to-electronic upgrade. The A1 Cardone 30-2690 part number is explicitly recommended by the Ford six-cylinder community as the Duraspark II upgrade distributor. The EP-2690 provides this upgrade path in a new replacement unit.
Do I need to reset the timing after replacing the Ford EFI distributor?
For most Ford EFI applications (1984 and later with EEC-IV), the base timing is computer-controlled and not adjusted with a timing light after distributor replacement -- provided the distributor is installed in the same orientation as the original. Mark the rotor position and housing alignment carefully before removing the old distributor, and install the new unit in the identical position. For 1983 EEC-III and earlier Duraspark-equipped vehicles, base timing IS field-adjustable and requires setting with a timing light after installation. For classic FE era vehicles (pre-1975), timing must always be set with a timing light after distributor replacement. Consult the factory service manual for your specific vehicle year and engine.
How do I order the EP-2690 for export or wholesale?
EP supports single-unit orders for market sampling, carton quantities for repair shops and parts counters, and container-volume wholesale orders. Standard production lead time is 15-30 days. OEM branding and private-label packaging are available for qualifying volumes. Contact our team via the inquiry form or WhatsApp for pricing and availability.
