Timing chain (unlike older belt-driven models), which reduces long-term maintenance costs.

For high-quality replacement parts, including certified used engines, retailers like Be Forward Japan are frequently used by the automotive trade for sourcing.

The inclusion of VVT-i means the intake camshaft features a hydraulic actuator sprocket. This sprocket advances or retards valve timing based on oil pressure signals from the Engine Control Unit (ECU), optimizing torque across the RPM range.
