More From Forge Motorsports:
Forge Motorsport has developed the FMINDK43, an upper airbox for the Toyota GR Corolla and Yaris GR, designed to enhance airflow and engine performance. While the stock airbox performs well with the standard engine map, its airflow and directional capacity are limited. The FMINDK43 addresses these issues by increasing the inlet diameter from 80mm to 89mm, resulting in around a 20% volumetric increase in airflow. Combined with the Forge Motorsport Inlet Duct (FMINLD1), this setup ensures a steady supply of cold air. The team opted for a cone filter instead of the stock panel filter after rigorous testing, using 3D scanning and real-world testing on both the road and dyno to fine-tune the design and maintain optimal performance while preserving drivability.

Testing revealed significant performance improvements, including peak gains of 13 bhp and 8 Nm of torque at the wheels, with noticeable improvements in power delivery from 2000 to 3600 rpm. The FMINDK43 works seamlessly with other Forge products, such as the FMTIA8 turbo inlet adapter, which increases the inlet tract's volume by 53%, ensuring a smooth flow of air to the turbo. This increase in airflow results in improved acceleration, especially after deceleration or gear shifts. Constructed from high-quality carbon fiber with an anti-UV gloss finish, the FMINDK43 not only improves performance but also adds a sleek look to the engine bay.
