BLOX Racing Honda & Acura 5.5mm Valve Stem Seals Blue FKM - Set of 8 (1988-2009)

BLOX Racing 5.5mm valve stem seals in blue FKM material come as a set of 8 for intake and exhaust valves on Honda and Acura engines with 5.5mm stems. These seals fit Civic, Integra, RSX, Accord, Prelude, S2000 and more from 1988-2009. They control oil metering to lubricate valve stems, block oil from the combustion chamber and handle heat up to 400°F in high-performance applications.

Key Features

  • Durability: Blue FKM (Viton) construction resists heat to 400°F, aggressive fuels, oils, chemicals and abrasion for longer service life than rubber or polyacrylic seals.
  • Performance: Maintains oil control for valve lubrication while preventing combustion chamber contamination to support power and efficiency at high RPM.
  • Dual Valve Spring Fit: 5.5mm design clears dual valve spring setups without issues common in OEM seals for high-RPM Honda builds.
  • Specifications: Valve stem 5.5mm, seal OD 12.9mm, guide OD 11.0mm, height 10.10mm for direct fit on B, D, K, H, F-series engines.
  • Engine Protection: Reduces valve guide wear and oil leakage to promote reliability under demanding conditions.

Product Notes

  • Confirm 5.5mm valve stem size on your engine before purchase.
  • Pair with BLOX Racing high compression valves (BXPT-20200) and titanium retainers (BXPT-10403) for complete valvetrain setup.
  • Lightweight design at 0.1 lb per set for easy handling.

Installation Notes

  • Professional installation recommended.
  • Valve spring compressor tool required for seal installation.
  • Works with stock or aftermarket valve guides such as BC3900/3901.
