Power Block Spacers for Toyota GT86 & Subaru BRZ

Power Blocks for GT86 & BRZ Specifications

On N/A vehicles, air intake is crucial and plays a large role in the vehicle's overall performance. The boxer engine on the Toyota GT86 and Subaru BRZ suffers from a weakness in the intake manifold : being quite compact, it chokes the air flow before it enters the engine.

These "plenum spacers" or "power blocks", allow you to raise the intake manifold 25 mm, lengthening the intake runners. Volumetric efficiency of your Intake Manifold is increased, reducing pressure drops and improving cylinder filling at all speeds (especially if your car is equipped with an intake kit).

Kit contents :

• 2 x digitally cut, forged aluminium spacers
• O-rings
Bolts and all required accessories for installation
• Silicone hose and coupling that allows you to lengthen the PCV (OEM hose for recyling the oil vapours)

The installation of the "power blocks" is quite simple, it takes about 1 hour with standard tools (socket and wrenches, cutting pliers...) and requires no extra modifications. These spacers can add up to 10hp, allowing you to reach maximum torque about 300 rpms sooner than OEM. An extremely cost effective and efficient modification for your GT86 or BRZ !
