Bosch 74MM DBW throttle body weld flange

Billet aluminum flange to bolt a Bosch DBW 74mm throttle body to a 4″ tube.  This flange is made with M7x1 threads (instead of the M6x1 threads normally) and will require you to slightly drill out the bolt holes in your throttle body for the larger bolts.  This larger bolt ensures the throttle body is secure under boosted applications.

Use M7x1x40 Socket Head Bolts with this flange.

Oring is included.
