The next evolution in Dual Port technology!

Offenhauser 6284 – Ford 240/300 High Performance Dual Port Intake Manifold

The next evolution of the legendary Offenhauser Dual Port!
Offenhauser’s new High Performance Dual Port Manifold (Part #6284) brings fresh power to the Ford 240 & 300 Inline 6. Designed and tested for performance, this updated version of the classic 6019 DP delivers stronger torque, improved throttle response, and more top-end power.

Featuring redesigned plenum geometry, expanded airflow passages, and modified dividers for high-RPM breathing without losing low-end grunt, the 6284 HPDP offers the best of both worlds — efficiency and performance.

Includes intake manifold, gasket, carb adapter plate, mounting hardware, and Offenhauser decal.
Proudly Made in the USA
