The G2X B58 Eventuri intake optimizes airflow while maintaining low inlet temperatures. Positioned near the exhaust manifold, the stock intake suffers from heat soak, reducing performance. To combat this, Eventuri designed a fully sealed airbox with a gold-reflective heat shield and an added secondary feed from the wheel arch for improved airflow.
The enlarged airbox maximizes volume, accommodating potential strut braces, while a smooth carbon intake tube replaces the stock convoluted design, tapering from 111mm (4.4″) to the turbo inlet for better flow. A custom high-flow dry filter with increased filtration area ensures optimal performance.
