Overview

The Forge Motorsports FMTIA8 is a turbo inlet adaptor designed for the Toyota Yaris GR. It consists of a billet machined turbo adaptor, two 5-ply silicone hoses, and a mandrel-bent alloy hard pipe. These components work together to provide a smooth and free-flowing path to the turbo, removing OEM restrictions and increasing the intake tract size from 48mm to 63mm.
Show original supplier description
The Forge Motorsport Turbo Inlet Adaptor (FMTIA8) is engineered to optimize airflow and boost performance for the Toyota GR Corolla and Yaris GR (GZEA14 G16E-GTS 1.6L 3-Cylinder Turbo). By replacing restrictive OEM pipework, including ribbed areas and noise chambers, this adaptor increases the critical inlet diameter from 48mm to 63mm. This design functions similarly to a velocity stack, promoting smoother air delivery directly into the turbocharger. Constructed from durable 6082 aerospace-grade aluminum and CNC machined for precision, the FMTIA8 features a black anodized finish for enhanced protection and aesthetics. The complete package includes the billet-machined turbo adaptor, two 5-ply silicone hoses, and a mandrel-bent alloy hard pipe. This upgrade offers over 53% increased capacity compared to the stock component. Testing has shown average power gains of 4-5 bhp and up to 10 lb-ft of torque, with potential variations based on tuning and other modifications. Users may notice a subtle enhancement in engine acoustics. Forge Motorsport backs this product with a lifetime warranty on the silicone hoses and billet adaptor, ensuring long-term reliability and performance.
