1.Precise Phase Adjustment of the VVT System to Support Sporty Power Output
Via a high-frequency response spool (response frequency ≥45Hz, displacement accuracy ≤0.004mm), it receives signals from the ECU to precisely control the pressure (0.8-13.5bar) and flow direction of engine oil, distributing oil to the "advance/retard chambers" of the camshaft phaser with a phase adjustment error of ≤±0.5°. Under high-speed, high-load conditions (engine speed ≥4000rpm), it retards intake valve closing; combined with the engine’s high compression ratio (11.5:1), this increases maximum power by 6%-8%, meeting the Cayenne’s power demands for "track-style driving."
2.Dynamic Oil Pressure Management to Cover Lubrication and Heat Dissipation in All Scenarios
It dynamically adjusts the main oil gallery pressure based on operating conditions:
·Cold start (below -18℃): Maintains low pressure (1.2-1.8bar) to avoid excessive lubrication resistance from viscous oil, achieving a 99.4% cold start success rate;
·High load (climbing/track driving): Increases pressure to 10-13.5bar and boosts oil flow by 20%-25%, enhancing lubrication and heat dissipation for core components to prevent high-temperature oil deterioration;
·Idle speed: Stabilizes pressure at 2.5-3bar to reduce oil pump energy consumption, cutting idle fuel consumption by 0.25L/h and balancing fuel efficiency for daily commuting.
3.Adaptive Protection for Operating Conditions to Handle Complex Usage Scenarios
·Off-road wading (water depth ≤500mm): Dual-seal design (fluororubber ring + metal dust cover) prevents sand, mud, and moisture from entering, avoiding spool jamming;
·Prolonged high-speed operation: The valve body features a finned heat dissipation design that increases heat dissipation area by 30%, preventing solenoid coil burnout due to high temperatures (>160℃);
·Oil deterioration warning: If oil pressure fluctuation exceeds ±1.5bar for more than 10 seconds, it triggers ECU fault codes (e.g., P0017/P0021) to prompt maintenance.
1.Porsche OE-Level Adaptation, No Modification or Error Codes
Manufactured in strict compliance with OE standards, its interface dimensions (oil gallery aperture error ≤0.01mm) and electrical signal protocol are fully compatible with M48 series engines, fitting Cayenne 955/957 models for direct replacement without modification. It avoids issues common with aftermarket parts (14% oil leakage rate, 9% ECU incompatibility error rate) and is compatible with the Porsche PIWIS Tester original diagnostic system.
2.High-Performance Durable Design, Longer Service Life Than Aftermarket Parts
·Valve body: Made of high-strength forged aluminum alloy specified by Porsche (tensile strength ≥350MPa) with "hard anodization + PTFE coating," increasing oil corrosion resistance by 65%. It withstands extreme temperatures of -45℃~180℃ and oil pressure up to 13.5bar;
·Spool/coil: Martensitic stainless steel spool (hardness ≥HV600) offers excellent wear resistance, with a service life of 120,000-150,000km (vs. 50,000-70,000km for aftermarket parts); 180-class high-temperature resistant enameled wire coil (encapsulated in epoxy resin) has a failure rate of <0.5% (vs. ~8% for aftermarket parts).
3.Factory Wholesale Attribute, High Cost-Effectiveness for Bulk Procurement
·Price advantage: Bulk procurement prices are 20%-28% lower than retail (e.g., unit price drops to 580 RMB for orders of 100+ units, vs. 800 RMB retail);
·Quality consistency: Each batch has a sampling pass rate of ≥99.7%, reducing the 12% rework rate of aftermarket parts and improving maintenance efficiency for repair businesses.
