TechnicalComprehensive evaluation of the OE Focus ST intake system revealed the primary restriction as the OE plastic crossover pipe as well as the OE air filter. 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 air filter with 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.
