mountune 福克斯 ST 低阻力进气(银色)

2363-CAIS-AB Silver

The kit consists of a cast aluminum low restriction crossover duct available in a natural silver or painted black finish (with a detailed fin and logo), mountune/Samco silicone hose and clamps. This kit should be used with vehicles already equipped with a high flow air filter such as mountune PN 2363-AF-AA


  • Cast aluminum construction
  • mountune/Samco Silicone coupling hose
  • Installation is simple and only requires simple hand tools


Comprehensive 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. When coupled with the uniquely designed mountune 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.
