Description
Specifically engineered for Porsche’s high-output direct injection (DFI) and multi-point injection engine architectures, this NGK fuel injector delivers ultra-precise fuel metering and high-pressure atomization. Built to match rigorous OEM standards, it ensures optimal air-fuel mixture formation, maximum power output, and immediate throttle response under extreme high-RPM driving conditions. Designed with advanced anti-clogging internal geometries and superior thermal resistance, this component eliminates fuel delivery hesitation, misfires, and uneven combustion. It is a premium replacement solution for overseas automotive parts importers, Porsche specialists, and European performance auto parts distributors.
Technical Parameters
| Category | Specifications & Technical Details |
| Structural Design | Compact high-pressure pulse-driven structure integrating a built-in micron-level filter screen, high-sensitivity solenoid coil, precision needle valve assembly, and multi-hole micro-nozzle plate. |
| Core Material | Constructed with a high-permeability alloy steel magnetic core, austenitic stainless steel corrosion-resistant valve housing, and high-pressure-resistant FKM / Viton O-ring seals. |
| Energy Transmission | High-pressure fuel pulse spray transmission — works with ECU solenoid pulse signals to achieve millisecond-level precise opening and closing. |
| Circuit & Insulation System | Low-impedance / high-impedance precision-matched circuit with dielectric breakdown resistance exceeding 500V DC. Integrated high electromagnetic compatibility (EMC) anti-interference design ensures precise control by Porsche DME (Digital Motor Electronics). |
| Protection & Durability | Resistant to acid and ethanol corrosion in fuel. High-sealing O-rings prevent high-temperature oil vapor leakage. Stable operation from -40°C to +150°C under extreme engine bay temperatures and high fuel rail pressure. |
Applicable Car Brands & Models
Common warning signs include engine misfires, rough or unstable idling, noticeable loss of acceleration power, increased fuel consumption, strong fuel odor from the exhaust, and an illuminated Check Engine Light (CEL).
Yes, these NGK fuel injectors are manufactured strictly according to Original Equipment (OE) physical dimensions, electrical resistance, and flow rate parameters, ensuring a 100% direct plug-and-play installation without ECU remapping.
Porsche DFI engines require precise fuel atomization to support high compression ratios. Proper fuel pattern and spray angle prevent carbon buildup on intake valves, reduce detonation (knocking), and protect internal engine components.
Minimum Order Quantity (MOQ) depends on specific part numbers (SKUs). For fast-moving stocked SKUs, MOQ starts from 10–20 units. Lead times typically range from 3–5 business days for stock items to 15–30 days for factory bulk orders.
