This four bolt flange fits the HE221 5.5cm2 and 7cm turbos we sell. The 7cm2 housing HE221 has a 5 bolt flange but this 4 bolt flange will work. The kit includes:
- Cummins/DCEC Exhaust outlet connection, part number 3978390
- Metal gasket
- 4 x Hexagon Flange Head Cap Screw
Please inspect the bolt pattern on the back of the backplate and compare it to your turbo before ordering. This does NOT fit all HE221, HE211, etc so it is important you inspect your turbo.
