Product Overview
The 90913-02117 valve stem seal is precision-manufactured for modern Toyota high-efficiency VVTi engines, including the 1NZ-FE, 2NZ-FE, and 1ZZ-FE platforms widely used in Yaris, Corolla, and Prius models. Featuring a heavy-duty metal-clad outer casing chemically bonded with high-grade FKM elastomer, this seal maintains rigid press-fit retention in the cylinder head under continuous high-RPM vibrations and extreme thermal cycles.
Engineered to strict OE standards, IVOK valve stem seals deliver accurate micro-metering of oil along the valve stem to protect valve guides against friction wear while eliminating oil consumption, blue tailpipe smoke, and combustion chamber carbon buildup over an extended service life.
Key Features
- Rigid Metal-Clad Casing: Ensures firm press-fit installation in the cylinder head and prevents seal walkout under high RPM.
- High-Temperature FKM Compound: Resists continuous operating heat up to 200°C without hardening, cracking, or loss of elasticity.
- Precision Calibrated Spring Tension: Delivers consistent radial lip pressure for exact oil metering and dependable leak-proof sealing.
- Direct 100% OE Replacement: Built strictly to OEM 90913-02117 dimensional tolerances for hassle-free fitment and zero oil consumption.
