The Racer X Fabrication intake manifold for the 2022+ Toyota GR86 / Subaru BRZ is designed to increase horsepower and torque.

The intake manifold starts with our CNC machined cylinder head flanges that are designed from the OE CAD data and modified to increase air flow. The flanges work with the OEM fuel rails or aftermarket fuel rails. We use separate mounting brackets that allow for simple installation or disassembly of the fuel rails. The runners are mandrel bent and formed to match the cylinder head flanges and base plates at the plenum. The plenum is made from 5052 aluminum and formed to meet the base plates, as well as the throttle body flange. At the back of the plenum there are 4 NPT ports for vacuum reference. The base plates features tapered velocity stacks to increase air speed and smooth airflow into the runners. The complete manifold is TIG welded, and uses common size O-ring seals for the flanges and throttle body.
