GDI Fuel Injectors and Direct Injection Fuel Nozzle Set; Manufactured with a stainless steel calibration slide and high-precision internal spring assembly; Engineered to maintain factory-specified fuel delivery volume and structural integrity under high-pressure cycles. Addresses engine misfire and rough idling symptoms; Engineered to resolve diagnostic codes associated with P0300, P0301-P0308, or fuel rail pressure inconsistencies; Restores the mechanical coordination required for GDI high-pressure combustion cycles. Constructed from laser-welded stainless steel for sustained thermal exposure endurance; Features a precision-ground spray tip to maintain original fuel delivery geometry; Internal components are tested for chemical stability during prolonged fuel exposure. Requires professional installation due to high-pressure fuel rail integration; New high-pressure fuel seals and O-rings must be seated according to factory torque specs to ensure a secure seal; Replaces OE 12668390, 12672368, 12656932, 12668649, FJ1217.

Hardware Physical Specifications:
- Injector Type: GDI (Gasoline Direct Injection)
- Body Material: Laser-Welded Stainless Steel
- Internal Components: Stainless Steel Calibration Slide & Spring
- Connection Type: OE-Matching Electrical Plug

Technical Restoration Characteristics:
This direct injection nozzle addresses pressure delivery issues within the fuel rail system. By restoring the precise mechanical energy transfer and timing of the fuel spray, it maintains the structural integrity of the high-pressure combustion cycle. All units are flow-tested to match factory-specified volumetric parameters.

Mandatory Installation Advisory:
The fuel system is under extreme pressure; depressurize the system before service. Injector seals and clips are designed for one-time use; replacement of the Teflon seal and the upper O-ring is required for a secure integration. Ensure the injector bores are completely clean of carbon buildup before seating. Professional-grade injector pullers and seal installers are highly recommended to prevent internal component damage.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $27 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for ZYFZZDS products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
