Crawford Billet Power Blocks- 13+ Subaru BRZ & Scion FR-S
**This item ships free**
The Billet Power Blocks from Crawford serve as a spacer for in between the intake manifold and the heads. This added space lengthens the intake runners and enhances the volumetric efficiency of the engine. By doing so, Crawford claims an increase of 19hp and 15ft lb of torque with a narrower torque dip by 300rpm. This was all on a totally stock BRZ with no tuning done. The blocks will work with aftermarket tunes and engine components as well. The BPB kit consists of 23 total pieces to be installed for a full bolt on system in under an hour. Kit includes 2 Billet Power Blocks, 4 delrin O-rings, 11 mounting bolts, 1 nut, 4 fuel rail shield risers, and 1 support bracket for the direct injection control unit.
