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.

- 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.

- Engine Protection: Reduces valve guide wear and oil leakage to promote reliability under demanding conditions.
