GrimmSpeed's cold air intakes for the Scion FR-S /Subaru BRZ / Toyota 86 were designed to increase power through the RPM range safely without custom tuning. They were also designed to be installed without removing the front bumper, which makes installating these Scion FR-S/Subaru BRZ intakes quick and easy.
The design of this intake started with months of hands-on research. Using a FARO Arm, GrimmSpeed was able to MAP the engine bay in 3D to ensure a perfect fitment. They used that working envelope to maximize performance by eliminating the 90 degree bend just before the airbox. They found that this contributed to decreased resistance, but also helped with accurate MAF readings.The MAF sensor was located inside the airbox to ensure that the heat from the motor and headers didn't skew it's readings.
With a solid theoretical foundation and a number of prototypes, Grimmspeed engineers hit the dyno. Working with a very well respected tuner, they tested 26 different intake configurations with over 140 dyno pulls. Armed with a massive amount of data, design decisions were made and we moved forward into production.
In true GrimmSpeed fashion, no corners were cut in the fabrication of each and every one of these intakes. The airbox is laser cut, CNC bent, riveted together and threaded inserts are installed before the entire assembly receives a heavy duty black wrinkle powdercoat. MAF flanges are CNC machined from 6061 aluminum and the intake tube is fabricated from custom bent tubing, made specifically for our application, to provide the perfect MAF diameter. The air straightener is laser cut from the same 6061 material and tumbled before the entire assembly is TIG welded by our expert welders. After welding, each tube is inspected and ported as needed to ensure maximum performance.
The intake provides gains in horsepower and torque across the entire rev range. This includes gains of 3-4 ftlbs in the "torque dip," and peak gains of 6 horsepower as measured at the wheels on a Dyno Dynamics dynomometer (reads lower than the common Dynojet). These gains are not achieved through MAF trickery either, as the air to fuel ratio remains nearly identical to the factory's. Additional gains in the top end can be achieved by modifying your factory snorkel (around 2whp).
