One-stop Purchase Fuel Injector Seal Ring 99970757440 for Porsche Macan (Made in Germany)

Core Selling Points

Premium sealing accessory for centralized bulk procurement

Fully consistent with OEM dimensional parameters, direct assembly without any modification

Applicable Vehicle & Installation Information

• Main applicable model: Porsche Macan (2.0T / 3.0T / 3.6T gasoline versions)
• Compatible extended Porsche models: 911, Cayenne, Boxster, Cayman, Panamera adopting the same injector sealing structure
• Installation position: Upper dynamic sealing part between fuel injector and fuel rail

Optimized German Raw Material Structural Design

1. Imported high-performance fluororubber raw material from Germany: outstanding heat resistance, gasoline corrosion resistance and anti-aging performance, adapting to the high-temperature working environment of Porsche high-power engines
2. Precision one-step molding process: smooth and flawless surface, uniform cross-section, stable compression rebound performance under long-term pressure
3. Accurate dimensional tolerance control: zero gap fit with the sealing groove, effectively prevent pressure loss of the fuel system
4. Stable physical property under temperature alternation: not easy to deform or crack under cold start and high-load working conditions
5. Independent finished single-piece structure, ready for direct installation and replacement

Core Functions & Engine Protection Value

1. Form tight sealing between fuel injector and fuel rail to prevent gasoline and fuel vapor leakage under high fuel pressure
2. Maintain stable working pressure of the whole fuel injection system to guarantee accurate fuel injection volume of each cylinder
3. Avoid combustible gas accumulation inside the engine bay and eliminate potential fire risks caused by fuel leakage
4. Improve engine running smoothness, reduce idle jitter and optimize the overall fuel combustion efficiency

Solvable Common Fault Phenomena

• Gasoline odor emanating from the engine compartment after vehicle startup
• Unstable idle speed and obvious engine shudder when idling
• Delayed accelerator response and weak power output during acceleration
• Slow rise of fuel consumption data in the driving computer
• Fuel system low-pressure fault codes detected by vehicle diagnostic instruments
