Each mountune filter is manufactured using a multi-stage process resulting in a great fit and virtually no seepage of frame material into the filtration media producing the maximum available filter area.

  • Increased performance

  • Includes 'do not discard airbox sticker'
  • Lifetime warranty against manufacturing defects
  • As used in our m330 power upgrade
