Which cars it fits

  • Honda H22 and F20B (VTEC) engines

What to check

  • Dual springs wound from Japanese chrome-silicon wire: the inner and outer springs are mated with a slight interference fit and have different frequencies, so they do not resonate together.
  • Alpha retainers are made from ultrasonically inspected medical-grade titanium, CNC machined, with radius-cut edges for rocker clearance, lightening grooves and a reduced height; each one is inspected and serialized.
