Nostrum High Flow Direct Injection Injector Kit

Nostrum presents the H720-2106 High Flow Direct Injection Injector Kit, engineered to meet your performance needs with a revolutionary FA24F injector design. This kit delivers the same excellent spray quality and pulse width performance as its predecessor but offers a more robust supply solution with a significantly lowered price.

What differentiates Nostrum in the upgrade market is the impressive 24% flow rate increase compared to stock injectors. Moreover, our kit is the only direct injection injector upgrade available for the FA24 platform.

The set includes four batched and serialized injectors, complete with tuning data, and is compatible with E85 fuel. Designed for easy installation, the injectors are direct replacements featuring custom orientation spring clips that securely lock into the fuel rail. One injector is specifically crafted to accommodate the cast aluminium coolant crossover pipe, simplifying the installation process with an extended harness connector.

Nostrum injectors maintain the OEM equivalent spray pattern controlled by the factory ECU, with tuning via COBB recommended for optimal performance.

In crafting the FA24 injectors, we opted for OEM Subaru injector cores. This decision, however, posed challenges related to pricing and supply due to limited dealer availability, escalating costs. Undeterred, we revisited the design process to ensure a satisfactory blend of quality and cost-effectiveness without sacrificing the performance integrity that Nostrum is known for.

The FA24 injectors have been meticulously designed to fit seamlessly with the factory specifications, avoiding any compatibility issues with the stock WRX FA24 engine. One of the injectors has been ingeniously designed to navigate around the aluminium coolant crossover, making installation straightforward and economical.

While enhancing flow rate is crucial for boosting horsepower, various aspects must be considered when selecting fuel system upgrades. Larger injectors do not always equate to better performance; a poor spray pattern may lead to rough idling, reduced drivability, increased knocking, soot accumulation, and difficulties in tuning. Incorrect spray patterns may also trigger liquid fuel contact with cylinder walls, causing oil dilution and escalating wear on internal engine components.

To uphold a high standard of quality, Nostrum has invested extensively in advanced equipment and technology, ensuring that our injectors perform at an OEM level. Our engineering team designs injectors to work in harmony with engine air flow in the combustion chamber for enhanced fuel evaporation and a more uniform air-fuel mixture, resulting in superior combustion quality. This guarantees that our injectors will excel under various demands, from daily driving to achieving impressive quarter-mile times.

For an even greater performance leap, consider pairing your injectors with Nostrum’s HPFP upgrade for the FA24. With a flow capacity 37% greater than the factory pump, this upgrade not only enables you to harness torque earlier in the rev range but also enhances peak horsepower by supplying your new injectors with the necessary fuel. Purchasing the set together also offers significant savings.

Your investment is protected with a limited lifetime warranty on all Nostrum products. Each package includes everything required for installation, along with comprehensive instructions. Our customer support and calibration engineers are on hand to assist with any inquiries, from installation guidance to tuning tips.
