The Blower Shop™ Reverse Injector Adapter, with 4 injector ports on each side is built out of the same aircraft grade aluminum as The Blower Shop's industry-leading roots superchargers. Polished to a mirror-like finish, they not only match The Blower Shop's line of show quality polished blowers but they complete the seamless transition between the injector hat and the supercharger. TBS Reverse Injector adapter is made from 6061 billet aluminum that is O-ringed on both sides so no gaskets or messy silicone has to be used. It goes up 2″ and forward 3″. **Black anodizing available upon request. Special order, please call for details.**
