**Important K-series Retainer Info:

Supertech Titanium K-series retainers require the use of either OEM K-series dual-valve-spring keepers or Supertech brand keepers for proper fitment. Keepers from a single valve spring equipped K-series engine are incompatible with Supertech titanium retainers. Honda changed the OEM keeper groove angle on all 04+ K20-series engines (ie. single valve spring equipped) making them incompatible with all dual valve spring retainers.
