Core Selling Points

Cost-effective sealing accessory for centralized one-stop purchasing

100% OEM dimension matching, direct installation with no modification required

Applicable Vehicles & Engines

• Matching engine: 3.0 TDI V6 common rail diesel engine (engine code: CATA, CRC, CRCA)
• Main applicable vehicle: Imported Audi Q7 4L chassis (2009–2015)
• Compatible models: VW Touareg, Audi A6 C6/C7, A8 D4 equipped with the same 3.0TDI power unit
• Installation position: Fastening and sealing component on the top fixing end of cylinder head fuel injectors

Optimized Durability Structure

1. High-strength stamping steel body: Excellent structural toughness, free from thermal deformation under long-time high temperature conditions
2. Integrated high-temperature fluororubber seal: Great compression resilience, oil resistant and anti-aging to effectively prevent diesel seepage
3. Precision positioning holes: Align perfectly with original bolts for even stress distribution after tightening
4. Anti-rust surface treatment: Resist corrosion from engine bay oil mist and diesel liquid
5. Finished product with integrated sealing structure, ready for direct installation

Core Functions & Engine Protection

1. Secure and lock fuel injectors to prevent displacement and loosening caused by engine vibration
2. Form effective sealing on the upper installation position of injectors to stop diesel leakage and blow-by gas escape
3. Reduce carbon dirt accumulation around injector holes to maintain a clean working environment for injectors
4. Stabilize fuel injection status and ensure normal combustion of each cylinder of the diesel engine

Malfunctions That Can Be Fixed

• Diesel seepage and oil marks around cylinder head injectors
• Unstable idle speed and obvious engine shudder
• Hard cold start with long cranking time before ignition
• Thick black exhaust smoke during rapid acceleration
• Excessive carbon buildup on injector surface worsening fuel atomization performance
