The mountune high-flow, low-loss cast crossover duct fully exploits the package space available, provides an increased internal volume and is available in a satin black finish (with detailed fins and logo).
This option is aimed at those that have already bought the mountune high-flow induction hose and air filter already, or that plan on using third-party options.
Also included is a mountune silicone coupling hose (available in three colours) and two high quality stainless steel clamps.
The mountune crossover duct can also be installed either with, or without the engine cover fitted.
mountune's engineers have developed a revised high-flow cast aluminium crossover pipe with smooth air flow characteristics and no internal obstructions, which improves intake air flow directly into the turbocharger.
Please note: Underbonnet sound deadening panel should be removed to ensure adequate clearance and also to allow you to fully appreciate your RS' 'real' induction noise.
