1.Energy Saving & Emission Reduction, Compliant and Worry-Free
It reduces residual hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxide (NOx) emissions, meeting China VI b and Euro 6d standards. Compared with faulty parts, it lowers fuel consumption by 7%-10% (the Mazda 3 2.0L Skyactiv model saves approximately ¥1,000-1,500 in annual fuel costs), balancing energy efficiency and environmental protection.
2.Engine Protection & Stable Operation, Reducing Fault Risks
Its OE-designed involute tooth profile ensures precise meshing with the timing chain (clearance ≤0.03mm) for stable power transmission. It real-time corrects phase deviations to avoid valve-piston collisions in high-compression-ratio engines, extending the engine’s service life.
3.Optimized Driving Experience, Enhanced Comfort
It reduces engine vibration by 18%-25% at idle (750-850RPM) to minimize in-vehicle noise; optimizes power continuity at low speeds (1,000-2,000RPM) to reduce shift jerking, making it suitable for urban commuting.
1.Factory-Direct Supply, Outstanding Cost-Effectiveness
By eliminating middlemen, it is 40%-55% cheaper than OE parts and only 15%-20% more expensive than ordinary aftermarket parts—while matching OE performance. Its after-sales repair rate is <2% (far lower than the 30%+ rate of ordinary aftermarket parts), making it ideal for bulk stocking.
2.High-Strength Material for Wear Resistance, Longer Service Life
Made of SCM440 alloy steel with carburizing and quenching (hardness HRC 60-63), it withstands 190℃ high temperatures and 22MPa high oil pressure. Equipped with imported fluororubber seals to prevent leakage, it has a service life of 90,000-130,000 km (2-2.5 times that of ordinary aftermarket parts).
3.100% Inspection & Warranty, Easy Installation
Before delivery, each unit undergoes four core tests: hydraulic response (delay ≤0.25s), sealing, dynamic balance, and high-temperature durability. It comes with dedicated seals and an installation manual; average technicians can complete installation in 1.5-2 hours, saving labor costs.
