NHP is always working to find solutions for your product needs! This new FA24F injector design provides all the same spray quality, min-pulse width performance, and flow increase as our original, but now with a stronger supply solution and a new lower price!
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 with custom orientation spring clips to lock into the fuel rail, with one injector out of the set expertly engineered to clear the cast aluminum coolant crossover with an extended and repositioned harness connector to simplify installation.
OEM equivalent spray pattern
OEM ECU controlled (COBB tuning recommended!)
When we set out to make an upgrade for the FA24, the obvious choice was to use OEM Subaru injector cores. This made pricing and supply difficult, as we were heavily limited by dealer network availability, and were stuck paying dealer prices. When the supply dried up, we went back to the drawing board to find a viable and cost-effective solution, without compromising the NHP quality and performance that you already know and love.
The all-new FA24 injectors have been carefully developed to fit like factory and have no compatibility issues with a stock WRX FA24 engine. One of the injectors has been specially engineered to clear the cast aluminum coolant crossover pipe with an extended harness connector lead. This makes installation far simpler for the end user and allows us to use a much more cost-effective injector core!
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!
Peace of mind.
Every Nostrum manufactured part is backed by a limited lifetime warranty. Our products are comprehensive solutions that come complete with everything you need inside the box, including detailed installation instructions. Tuning guides are also available for your dealer or tuner. We have customer service and calibration engineers on staff to provide you with any support that you may need, from installation to tuning.
