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.
