NISSAN A5208-43G0A-01 Oil Filter

This genuine Nissan (OEM) oil filter (part number: A5208-43G0A-01) provides premium-quality filtration for the engine lubrication system. Original OEM parts ensure a precise fit and maximum reliability, protecting the engine from premature wear and damage.

Technical Features and Operating Principle

• Effective Microfiltration: The specialized paper- or synthetic fiber-based filter media effectively removes microscopic soot particles, metal shavings, dust, and other combustion by-products from the engine oil.
• Anti-Drainback Valve: Prevents oil from draining back into the oil pan after the engine is shut off. This ensures that adequate oil pressure is immediately available upon the next startup, minimizing cold-start wear.
• Bypass Valve: A critical safety feature that maintains oil flow during cold starts (when the oil is thick) or in the event of complete filter clogging, preventing the engine from running without lubrication.
• Pressure-Resistant Housing and Precision Seal: The robust metal canister withstands high system pressures and temperature fluctuations, while the specialized rubber gasket ensures a leak-free seal.

Importance of the Oil Filter and Maintenance

The oil filter functions as the engine's "kidney". Over time, accumulated contaminants saturate the filter media, reducing flow capacity. In accordance with manufacturer specifications, the oil filter must be replaced at every engine oil change.

Typical Signs of Wear or Clogging:

• Low oil pressure warning light illuminated on the instrument cluster.
• Unusual metallic knocking or ticking noises from the engine (due to insufficient lubrication).
• Engine overheating as a result of increased internal friction.
• Dark, thick, and heavily contaminated engine oil visible on the dipstick.
