This genuine oil filter is specifically engineered to ensure the longevity of Toyota engines. It guarantees uninterrupted oil circulation and effective cleaning, which is critical for the Variable Valve Timing (VVT-i) systems equipped in Corolla 1.8 engines.

Technical Specifications

• Part Number: 90915-YZZN1 (Compatible replacements: 90915-10003, 90915-10001).

• Application: Toyota Corolla with 1.8L engines (1ZZ-FE, 2ZR-FE, 2ZR-FAE).

• Type: Spin-on.

• Dimensions: Compact housing optimized for the Corolla engine bay.

Key Advantages

1. Effective Microparticle Filtration High-quality filter media traps carbon deposits, wear products, and dust particles, protecting the cylinder walls and crankshaft journals from abrasive impact.

2. Anti-Drainback Valve A reliable rubber valve retains oil in the upper part of the engine after it stops. This prevents "oil starvation" during cold starts and reduces component wear in the first seconds of operation.

3. Bypass Valve In cases of extreme cold (when the oil is too thick) or severe filter clogging, the bypass valve ensures direct oil flow to engine parts, preventing failure due to lack of lubrication.

4. High-Quality Sealing The specialized gasket is resistant to high temperatures and aggressive modern motor oil additives, eliminating leaks throughout the entire service life.
