About Product
This series of High Performance Fuel Injectors is made for extreme performance and tough working conditions. It uses nano-ceramic coated valve needle technology to achieve industry-leading flow accuracy of 1% under 6.0 Bar high pressure. It can handle everything from classic muscle car E100 ethanol modification to 8000RPM track racing.
The main new features are a 90° wide-angle ultra-fine atomizing nozzle (particle size ≤ 20μm), which greatly lowers the chance of turbo engine detonation, and a self-cleaning valve seat system that keeps the valve seat from getting clogged with fuel residue. This means the engine can last for 400,000 miles, even in the desert or in very cold temperatures of -40℃. It works with the original ECU and most popular competition tuning protocols, so it can be replaced and upgraded without changing the fuel line.
This lets users boost power output by 18% while cutting maintenance costs by 32%, setting new standards for Racing Fuel Injectors in terms of power, durability, and economy.
Products Advantage
Our 50 LBS High Performance Fuel Injectors are designed to work well on both the track and the street.
They use the latest technology to promote accuracy, durability, and flexibility. Laser-calibrated nozzles deliver unequaled ±1% flow constancy, avoiding AFR imbalances that cause engine knock or power loss-critical for racing fuel injectors requiring split-second throttle responses. These injectors have aerospace-grade ceramic core valves that protect them from damage caused by ethanol and give them 20% finer fuel atomization than ordinary ones.
This makes combustion more efficient in turbocharged or supercharged setups. The EV6 OEM connectors and plug-and-play architecture make it easy to connect to popular platforms like Ford EcoBoost and Toyota 2JZ without having to pay for expensive ECU remapping when you replace out your standard engine.
316L stainless steel housings with IP67-rated seals can handle saltwater exposure (as shown by 2,000-hour ASTM B117 salt spray testing). This makes them great for marine engines or off-road tractors. Need customization? Adjust spray angles between 30° to 90° or scale flow rates from 800cc to 2,200cc without minimum order quantities-perfect for tuners targeting certain RPM bands.
Thermal-resistant FKM-XR seals prevent leaks even under 200°C turbo heat soak, while a 150,000-mile lifespan provides reliability for daily-driven performance cars.
Every unit is dynamically flow-matched on Bosch EFI benches to make sure that they can be used with any other unit and that they are all the same. This is in line with SAE J2682 and ISO 9001 requirements.
Main application scenarios
Drag racing (NHRA-approved events and professional teams)
It is a standard product in the world of racing fuel injectors and is made for V8 supercharged engines like the Ford Coyote 5.0L and the Chevrolet LT4.
With a flow tolerance of 1% at pressures below 6.0 Bar, each cylinder gets the same amount of fuel, which means there is no chance of detonation in the 0-400m sprint of high-supercharged engines. The high-performance fuel injector uses 90° wide-angle atomization technology, works with a throttle with a diameter of at least 90 mm, and has a basic flow rate of 1200 cc/min.
It can support speeds of up to 8,000 RPM (NHRA certified, compatible with Nitro methane fuel), which helps drivers break time records on the 1/4 mile track.
Rock climbing and crossing the desert off-road (Rubicon Trail/Dakar Rally)
The heavy-duty fuel injector that works best in tough terrain has been used by hardcore off-road teams such the Jeep Wrangler JL/JT and the Toyota LC300.
The 30G anti-vibration valve body passed the SAE J1455 vibration test and can handle impacts at 40Hz. The IP67 waterproof seal and 316L stainless steel shell make it easy to handle mud and sand erosion up to 800mm deep.
Its low failure rate (<0.3%/1000 hours) makes it the best upgrade option for teams that want to cross deserts or explore rainforests compared to regular fuel injectors.
Heavy-duty commercial diesel transportation (logistics across borders/mining machinery)
The high-performance fuel injector for Volvo D13K and Cummins X15 heavy-duty engines has nano-ceramic-coated valve needles that can stop B20 biodiesel from corroding (pH≤4.5). This extends the service life to 400,000 miles and cuts the fleet's maintenance costs by 32%.
The 2200cc/min dynamic flow accurately responds to the load fluctuations of the 60-ton semi-trailer (Scania R730), ensuring the stable fuel supply of the turbocharger when climbing with full load, redefining the efficiency benchmark of Fuel Injector in the field of heavy-duty transportation.
Modification of classic muscle vehicle ethanol fuel (E85/E100 compatible)
The ethanol-ready fuel injector made just for American V8 historic automobiles (such the 1969 Camaro ZL1 and the 1970 Hemi Cuda) fixes the original fuel injector's problem with ethanol compatibility.
FKM-XR fluoro rubber seals can withstand powerful solvents like E100 and can be replaced immediately without changing the fuel line. The air-fuel ratio is automatically adjusted to the best value of 10.5:1 ethanol, which frees up 15% of wheel horsepower. This lets classic cars get back into the race in the new energy era.

Frequently Asked Questions
How can I be sure that your High Performance Fuel Injector will work with my engine?
-
We have a cross-reference database of models and engines that supports over 300 popular models, including the Ford Coyote 5.0L, Chevrolet LT series, and Honda K20C1. Please key in your VIN code or engine code on the product page. The system will then automatically match the specifications, such as flow, interface type, and resistance value. You can also call customer care to get help with specific adaptation solutions.
Do you have to use racing ECUs with racing fuel injectors?
-
No. By default, our injectors work with Haltech, AEM, and other racing ECUs, as well as original OBD-II systems (resistance range 12–16Ω). For turbocharged or nitrogen-accelerated modified automobiles, though, it is best to turn on multi-pulse mode to take advantage of the high flow rate of 2200cc/min.
How much more horsepower can your device add compared to regular Fuel Injectors?
-
The actual measured data changes based on how the engine is running. For instance: The Garrett G30-900 turbine on the EVO X may raise the wheel horsepower by 18% at a boost pressure of 1.8Bar after using the high flow fuel injector. This is because the original fuel injector doesn't let enough flow through.
Can your Ethanol-Compatible Fuel Injector be used instead of the original fuel injector?
-
Yes. All E85/E100 compatible models include a plug-in design (standard USCAR interface) and built-in FKM-XR fluororubber seals. You can install them right away without changing the fuel line. They work with muscle vehicles from 1960 to 2023.
How can you keep sand and grit from getting into the Fuel Injector in desert off-road scenes?
-
Our Off-Road Fuel Injector comes with a 50μm pre-filter that can be removed and washed, as well as an IP67 sealing structure. It can still keep a flow stability of ±2% even after being in sand and dust for a long time. Every 500 hours, you should check the filter.
