Product Details

Part Number:	VS-H6.6I-8
Brand:	Supertech

The Supertech VS-H6.6I-8 is a premium set of intake valve stem seals engineered for performance Honda / Acura LS-series engines. Manufactured from high-grade polyacrylic material, these seals are designed for high-performance and race applications where reliability, low oil consumption, and tight sealing are paramount. Supertech’s precision-engineered valve stem seals offer a dependable solution during engine rebuilds, especially for enlarged or modified guide designs.

Features:

6.6 mm Diameter: Specifically sized for high-performance or oversized valve stems to ensure correct sealing.
Polyacrylic Material: Provides superior wear resistance and sealing performance under pro-tuned temperatures without leaking.
Set of 8: Enough seals for a full 8-valve head (or a 4-cylinder with 2 valves per cylinder) — ideal for full rebuilds.
Reduced-Diameter Guide Compatibility: Designed specifically for “reduced-dia” valve guides used in LS-series or other performance heads.
Improved Durability: The polyacrylic compound is chosen for long-term reliability under repeated heat cycles and high-rev conditions.
Low Oil Consumption: Helps minimize oil “sucking” past the valve stem, aiding in consistent compression and cleaner combustion.
Affordable OEM-Quality Replacement: Competitive price point for high-performance race-grade seals — great for engine builders or DIY tuners.
Application Fitment: Commonly used on 1990–2001 Acura Integra (LS/RS/GS) engines per parts catalogs.

When you're building or rebuilding a high-performance head with oversized valves or modified guides, the VS-H6.6I-8 offers the right mix of durability, sealing precision, and performance. These are not just “stock” seals — they’re tailored for serious engines, helping you maintain oil control and extend the life of your valvetrain even under hard driving or high-RPM use.
