Yes — the AiYiGu unit is explicitly made for the straight 6 cylinder 240 and 300 engines commonly installed in mid-20th-century Ford trucks. Confirm compatibility by comparing the distributor mounting and electrical connector to your original HEI028BK or factory distributor.

• Direct replacement for OEM part number HEI028BK.
• Suitable for Ford F100, F150, F250, E100, E150 models with 240/300 inline-6.
• Designed to match stock shaft length and mounting flange for bolt-up installation.

How does this AiYiGu distributor affect engine performance?

The distributor restores consistent ignition timing and provides a high-energy spark that helps support cleaner combustion and stronger ignition at higher RPMs. While not a tuning device, it helps the ignition system operate as intended, which can translate to steadier idle, improved throttle response, and more reliable starting.

• HEI-style 65K coil output at up to 7,500 RPM improves spark intensity.
• Stable timing feed reduces misfires and rough running under load.
• Durable internal components resist wear for long-term consistency.

What are the construction and quality features of the AiYiGu distributor?

The distributor is constructed with high-grade, hardened steel gears and a heavy-duty housing to resist wear and corrosion. Components are chosen to give long service life under typical driving and towing conditions, and the unit is finished to resist environmental exposure in older truck applications.

• Hardened steel drive gears for long-lasting mechanical reliability.
• Anti-corrosion finish to extend service life in exposed engine bays.
• Precision internal components to maintain accurate timing over time.

What should I know about installation and warranty?

Installation is typically straightforward for a mechanic familiar with HEI distributors, but correct timing setup is essential for optimal operation. AiYiGu recommends professional installation to ensure rotor alignment and static/dynamic timing are set correctly. The product includes seller support for troubleshooting or replacement if defects arise.

• Professional installation recommended for correct timing and reliable results.
• Compare electrical connector and vacuum advance (if applicable) before fitting.
• Contact AiYiGu customer support for warranty or troubleshooting assistance.

Who is this for: This distributor is intended for classic Ford truck owners, mechanics restoring 240 or 300 inline-six engines, and fleet operators who need a direct-fit HEI replacement. If you want a rugged, OEM-replacement ignition component with hardened gears and verified part number compatibility (HEI028BK), the AiYiGu distributor is built to be a long-lasting option that simplifies return-to-service and routine maintenance.
