Both turbos feature a gold anodized 7/14 bladed billet aluminum compressor wheel that is lighter and stronger than the stock cast wheel to help provide quicker "spool-up" and higher air flow than the stock turbo setup. This turbo setup can be installed on the 2008-2010 6.4L (td) Ford F250/F350 Superduty as a direct bolt-on replacement. All connections to the vehicle are compatible with the OE geometry, resulting in a quick and reliable connection. Maximum gains are achieved from fuel system upgrades, either electronic or mechanical.
