Offenhauser 6227T Ford 240/300 Inline 6 Turtle Flow Insert

Start the new year with more power under the hood. The Offenhauser 6227T Turtle Flow Insert is a performance-enhancing upgrade engineered specifically for the legendary Ford 240 / 300 inline six when paired with the Offenhauser 6227C intake manifold.

Designed with airflow efficiency as the top priority, the 6227T installs directly into the floor of the 6227C manifold. Its carefully developed “turtle” geometry reduces internal airflow drag and turbulence, helping the intake charge move faster and more evenly to each cylinder. The result is a noticeable improvement in overall engine performance where it matters most.

Benefits include:

• Increased airflow and higher intake velocity
• Improved fuel distribution across all cylinders
• Sharper throttle response
• Gains in horsepower and drivability

The 6227T Turtle Flow Insert is available as an **optional upgrade with new 6227C intakes or can be purchased separately for existing setups. Installation is straightforward, and while there are multiple installation methods, Offenhauser’s recommended approach is welding the insert in place for best long-term performance and durability.

If you’re looking to wake up your Ford 240/300 inline six and get more out of your Offenhauser intake, the **6227T Turtle Flow Insert** is a simple, proven way to unlock better airflow and stronger performance.
