Original BorgWarner EFR exhaust gas housing
Here you receive a single exhaust casing for a BorgWarner EFR turbocharger. This allows you to change the A/R value or the installation position or the flange pattern of the turbocharger. The exhaust case comes original from BorgWarner.
Fits the following turbochargers:
BorgWarner EFR-6258 / EFR-6758
For exhaust wheel diameter: 58mm
A/R Value: 0.85

Other A/R Value?
With this exhaust casing you can drive a different AR value on your AirWerks turbocharger. If you order an AirWerks turbocharger and want a different A/R, you have to order this case separately and change it.
