Soler Engineering Adapter 90mm Throttle Body to 89mm (20212025 Ford F-150 5.0L V8) SE-ML3Z-90-89
Precision 90mm-to-89mm Adapter for 2021+ F-150 Coyote Manifolds
The Soler Engineering SE-ML3Z-90-89 Adapter provides a perfectly centered, step-free transition for upgrading to a 90mm throttle body on 20212025 F-150 5.0L applications. Using a self-centering OEM bolt pattern, this adapter keeps the throttle body, adapter, and manifold bores perfectly concentric, preventing airflow disruptions, bore mismatch, or power-robbing turbulence.
Its efficient tapered internal design maintains smooth airflow and prevents the abrupt pressure losses commonly found in straight-bore adapters. A military/aerospace-style sealing gland paired with a low-compression-set silicone seal delivers long-term reliability, preventing seal fatigue or compression set over time. Whether used with the stock manifold or an aftermarket supercharger, this adapter ensures accurate positioning, smooth airflow, and interference-free throttle operation.

FAQs
Why use a tapered adapter instead of a straight reducer?
Straight-bore adapters create abrupt transitions that drop manifold pressure. Solers tapered design maintains airflow speed and reduces turbulence for smoother, more efficient flow.
Is this adapter suitable for aftermarket superchargers?
Yes. It supports stock and supercharged setups, ensuring proper alignment, sealing, and interference-free operation when running a 90mm throttle body upgrade.
