Holset He221 back plate kit

Holset HE221W 4-bolt turbine housing back plate. This fits some 4 and 5 bolt Holset HE221W models. Please check the bolt pattern on your HE221W, as there are many variants, and this doesn't fit all HE221W models. This fits HE221W models with turbine housing sizes of 5.5cm or 6cm. Note that the 5.5cm and 7cm HE221W has a 5 bolt flange, but this 4-bolt plate is compatible.

This back plate makes installation easier, allowing you to use our 79mm exhaust adapter and V-band or our universal V-band dump pipe.

What's included:

- 1 x Back plate.
- 1 x Gasket.
- 4 x Hexagon flange head cap bolts.
