This also increases durability and reliability whilst optimizing the Turbos performance.
With a larger flow capacity and reduced resistance. The pipe was designed to be as straight as possibly allowed. The reinforced hose design allows the hose to maintain its structure during high boost conditions. This then assists the turbo obtain a stable consistent flow of air.
