The Supertech 5.5mm Viton Valve Stem Seal Set for Honda K Series keeps oil where it belongs even when your K20 or K24 is spinning past 9,000 rpm or gulping down ethanol-rich fuels. Each seal is molded from genuine DuPont Viton that shrugs off 400 °F cylinder-head temps, race-gas additives, turbo heat-soak, and daily-driver stop-and-go abuse. Why it matters Zero oil creep – Tight, 5.5 mm bore tolerances and a tensioned garter spring stop oil from sneaking past the valve guides, eliminating blue-smoke start-ups and oil-fouled plugs. Longer guide life – Micro-polished sealing lips meter the perfect film of oil to the valve stem, preventing metal-on-metal wear without starving the upper valvetrain.
