Mountune engineers have designed a revised replacement crossover pipe with smooth air flow characteristics and no internal obstructions to improve intake air flow directly to the turbocharger. Coupled with a uniquely designed Mountune high flow air filter with  dual inlet the Mountune High Performance Induction kit will provide increased air flow improved engine response and power. As there is no performance benefit and to help maintain the original vehicle's NVH quality we have elected to retain the OE coupling hoses and connectors when possible.
