The BD-Power 1044106 T3-T4 Adapter Flange provides an inexpensive alternative to replacing your exhaust manifold. With T4 sized turbine housings, there is no performance advantage to changing the exhaust manifold to match. So, why go through the expense? The BD-Power T4-T3 Manifold Flange allows you to adapt a T4 Turbocharger to your T3 manifold. Machine cut flat to 0.480, the BD adapter seals in exhaust drive pressure.

  • T4 Turbo - T3 Manifold Adapter

It may be necessary to drill out threaded holes in manifold or turbo to allow a stud to pass through.

t3 to t4
bought a s362 for my pickup and needed a adapter for T4, the back bolts didn't go in so I just throw on the front ones, I'm changing out my exhaust manifold in a month so I'm not to worried about it tbh.

Part fit as it should. No mods, easy install, and customer service is always great!
T3-T4 adapter flange
Fit perfectly. Did a 2nd gen swap awhile back with stock turbo, then upgraded to an s464 and needed the adapter flange as my manifold was a t3 and turbo is a t4. Gaskets and everything included. Very straight forward install.

Questions and Answers

Can this be used with a T4 manifold and a T3 turbo?
View Staff Answer 

No, the BD-Power T4-T3 Adapter Flange 1044106 is to be used only with a T3 manifold. This allows a T3 manifold to run a T4 turbo.

How thick is this adaptor?
View Staff Answer 
The adaptor is .475 (+/- .005) thick.

It’s very difficult to say exactly what you’d need. Your best bet is to call your local Ford Dealer with the last 8 digits of you VIN and ask them for the OEM number on the part you’re looking for. From here you will then be able to determine the item you’ll need based on cross referencing the OEM Part# with the part number of the replacement.
