What sets Nostrum apart:
- +24% flow rate increase over stock
- The only DI injector upgrade on the market for the FA24!
- Set of 4 batched and serialized injectors with tuning data
- E85 compatible
- Direct Replacement - same outline as the OE injector
- OEM equivalent spray pattern
- OEM ECU controlled (COBB tuning recommended)
These injectors have been carefully developed to fit like factory and have no compatibility issues with a stock WRX FA24 engine, meaning there’s no need to worry about secondary injection controllers, fitting secondary injector hardware, filling meth tanks, or clogged meth injectors. Being that they are compatible with the stock ECU, they are fully tunable with Cobb. NHP’s FA24 fuel system bundle has been available to private customers for more than a year and several cars have completed several thousands of miles of power and smiles. These products are now available to the public!
While increasing flow rate is critical to making more horsepower, there are other factors to consider when choosing fuel system upgrades. A bigger injector isn’t always a better injector! It can flow a large volume of fuel at WOT, but if the spray pattern is poor, you can expect poor idle quality, poor drivability, increased knock propensity, soot, NVH (noise vibration harshness,) and tuning difficulty. Additionally, the wrong spray pattern can result in liquid fuel impinging in the cylinder walls, causing oil dilution, which increases mechanical wear to internal engine components.
Nostrum has invested significant time and resources into acquiring the equipment and machinery necessary to deliver an OEM level of quality on our injectors. Our engineers design and develop injectors to optimally interact with engine air flow inside the combustion chamber to improve fuel evaporation and create a homogenous air-fuel mixture that results in a higher combustion quality. For you, this means that you can expect our injectors to perform at their absolute best regardless of what you are asking from them, from daily driver duty to setting new ¼ mile records.
Bundle up!
To take full advantage of your new injectors, we would recommend pairing them with Nostrum’s HPFP upgrade for the FA24. Flowing 37% more than the factory pump, the Nostrum HPFP will not only allow you to dial in more torque earlier in the rev range, but also gain peak horsepower by providing the upgraded injectors with the additional fuel that they need! Bundling the pump and injectors together saves you money!
