Features & Product Details

Comprehensive evaluation of the OE Focus ST intake system reveled 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 K&N air filter with removable end cap for those that desire more intake sound control, the mountune High Performance Induction kit will provide increased air flow, improved engine response, and power. To help maintain the original vehicle’s NVH quality, they have elected to retain the OE coupling hoses and connectors when possible.

• Cast aluminum construction
• K&N High Flow Air filter with end cap for intake sound control
• mountune/Samco Silicone coupling hose
• Installation is simple and only requires simple hand tools

mountune Low Restriction Intake Black ( Part Number: 2363-CAIS-BA)
Mountune Low Restriction Intake Focus ST  4 years ago
5out of 5stars

RalliSportDirect again kicked ass in all areas of their service... Mountune intake fitted up perfect and the pipe internal surface is so smooth and much larger than the standard plastic top pipe. Induction sound is noticeably louder but not obnoxious. You can hear a deep induction sound prior to boost building then you hear the whistle due to the conical exposed section of the filter. Cant claim any HP difference as it is just an intake but its all the little things that add up ;)

  • Q: K&N Filter Part Number  jzombie5 years ago

    What is the K&N part number for the filter that comes with this kit? I couldn't find it on Mountune's site. I did find a similar filter for the the Focus ST on K&N's site (E-9289) but I am not sure if it fits the stock airbox as the dimensions are different from the listed drop in replacement filter (E-2993). Thanks.
