About Product
Our fuel injectors are made to get the most power and fuel efficiency. They can handle dynamic flow rates of 500cc to 1200cc, which is perfect for BMW engines from daily-driven 318i commuters to turbocharged 850Ci V12 beasts. These high-performance fuel injectors have DLC-coated nozzles and ASNU flow-tested accuracy (±1.5%). They work perfectly with N42/N46/M70 engines and lower the risk of E85 ethanol corrosion.
Our solutions are perfect for drivers who want high-quality fuel injectors for BMW engines or E85-compatible fuel injectors. They lower the cost of fuel in cities by 12% and can handle turbo pressures of 3.0 BAR or more.
Solutions for Enthusiasts and Professionals in Bulk
We offer batch-matched sets (±1%) with OEM specs for everything from direct replacement fuel injectors that BMW collectors need for classic 850i restorations to bulk orders for repair companies.
Products Advantage
We make high-performance fuel injectors that are made just for BMW engines with a displacement of 1.8L to 5.6L, like the 318i, 325iX, 750iL, and 850Ci. They have flow rates that range from 500cc to 1200cc and can be adjusted to fit the needs of OEM ECU tuning or turbocharger changes. Using an ASNU dynamic flow meter, each injector is calibrated to a very tight tolerance of ±1% to 1.5%.
This makes sure that the air-fuel ratio (AFR) is balanced between cylinders. This fixes problems with BMW S50 and M70 engines that cause them to shake when they start up and run out of gas at high RPMs. The EV6/USCAR connector and 14mm sealing ring, OEM Part # 078133551, let you plug them directly into the factory gasoline rail without having to make any changes. This cuts installation time by 60% and makes sure they work with all BMW models.
Lasting in Tough Conditions
To protect against the corrosive nature of E85 ethanol fuel, the injectors are coated with DLC and use military-grade Viton seals. These can handle temperatures up to 150°C and fuel pressures up to 7 bar, which stops ethanol from getting into the engine and causing damage. The 1200cc high-flow version works well even when the BMW 850C Si twin-turbo V12 engine is running at its most extreme settings. The injection pulse width error is less than 0.02ms, which greatly lowers the risk of knock and extends the life of the engine.
Services for optimizing and customizing B2B procurement
We help wholesalers and brand owners buy in bulk by letting them choose their own flow rates and logos. The precision of within-batch flow matching is ±1.5%, which lowers the cost of calibration for fleet managers or modification shops. Depending on what you need, we can change the type of interface (such the EV1 interface for the BMW M70 engine), the flow parameters, or the color of the seal (we offer the Pantone color palette). We don't charge any fees for tools, and we can swiftly meet the needs of specialist vehicles. We follow the rules in the EU, the Middle East, and other places.
Main application scenarios
Daily commuting and getting the best gas mileage (BMW 318i/325i)
Our 500cc-650cc injectors increase fuel atomization efficiency at low rpm by precisely managing the air-fuel ratio for BMW 318i/325i engines with 1.8L-2.5L engines. Tests reveal that fuel use goes down by 8% to 12% when driving in the city, and they also fix the problem of N42/N46 engines shaking when they start up cold.
This is the best alternative for commuting and renewing and maintaining a used BMW because it works with the factory DME system and doesn't need any further ECU reprogramming.
Changes to the turbocharger and high-performance racing (BMW 850Ci/750iL)
For turbocharged M70 series 5.0L-5.6L V12 engines (like the 850Ci and 750iL), we have a high-flow option that works with 1000cc to 1200cc engines. It keeps the flow stable within ±1.5% at 3.0 bar turbo pressure thanks to ASNU dynamic calibration.
It works with twin-turbo kits like the Garrett GTX35R, which raises the maximum output to almost 600 HP and lowers the chance of knock when the engine is under a lot of strain. This makes it great for both track days and street driving.
Restoring a classic car to its original specifications (1990–2000 BMW 850i/850C Si)
These 550cc standard-flow injectors are made just for classic vehicle fans. They have an exact copy of the original EV6 connector and 14mm seals (OEM# 078133551) and work with the Bosch Motronic 1.2 system in the M70 engine.
Even for collector cars that have only been used a little, a DLC anti-wear coating keeps injectors from getting clogged when they are stored for a long time. This brings back the classic 1990s BMW V12 sound.
Ethanol Fuel (E85) Retrofit Compliance Solution for BMW 525iX and 325iX
The injector's internal Viton seal and 316L stainless steel valve body are TÜV E85-certified to withstand corrosion because ethanol absorbs water. This is good news for BMW owners who want to switch to ethanol fuel.
The 850cc version works with the xDrive system of all-wheel-drive vehicles like the 525iX. It is optimized for E85's large injection volumes, with a flow linearity error of ≤1.2%, which meets EU RED II standards and keeps conversion conflicts from happening during environmental testing.

Frequently Asked Questions
Q1: Will these work with the 5.4L V12 engine in my BMW 750iL?
+
-
A: Yes! OEM Part# 078133551 works with BMW engines that are 5.0L to 5.6L.
Q2: Do I need to adjust my BMW 325i with 850cc injectors?
+
-
A: No, not for stock engines. Modified builds (turbo or supercharged) need ECU changes.
Q3: How do these compare to Bosch injectors?
+
-
A: We fit Bosch's, however our flow tolerance is tougher at ±1%.
Q4: How can I be sure that your injectors will work with my 1995 BMW 850Ci with an M70 engine?
+
-
A: Our EV6 interface injectors (OEM# 078133551) are exact copies of the ones that come with M70 V12 engines. If your stock injector has a 14mm o-ring and a USCAR connector, you can plug it in without having to change any wiring.
Q5: Is it okay to blend new and old injectors on my N52 engine?
+
-
A: No. A flow difference of even 2% between injectors might throw off the AFR. We require batch-matching for BMW N52 engines, which means you have to buy a whole set of 6 injectors (±1% variance) to stop cylinder misfires.
