How does the 90915-10004 oil Filter improve fuel efficiency?
The 90915-10004 oil Filter shields hydraulic tappets, variable valve timing (VVT) components, and piston rings from wear. Worn parts lead to poor cylinder sealing, off‑calibration valve timing, or leaky VVT systems—all causing incomplete combustion. The filter keeps these parts within factory specs, ensuring the engine burns fuel efficiently without needing extra fuel injection to compensate for power dips.
