TOYOTA GT86 SUBARU BRZ CRAWFORD BIG POWER BLOCKS INTAKE MANIFOLD SPACER

This is one of the best performance upgrades get you! Do not hesitate and snatch a kit while you can. These new CNC machined power blocks from billet 6061 aluminum, sit between your cylinder head and your intake manifold, purely to get longer intake runners. The lengthened intake runners increase the volumetric efficiency of the engine which gets you an extra 19 horse power and 15lbs/ft of torque! And on top of that, the torque dip has been narrowed up by 300RPM on a completely stock FA20. Crawford BPB's sandwich between the cylinder heads and the intake manifold to create longer intake runners. As you can see on the dyno graph, torque went from 155 to 170 as well as BHP went from 187 to 206 All this works with all aftermarket tunes, exhausts and intake components. All that tested by Crawford.

Box contains all the fittings and bolts/nuts you need to install this kit. Approximate installation time is 30 minutes.
