About Product
Our direct replacement fuel injectors are made for the competitive high-performance fuel injector market and are the most reliable choice for turbocharged and ethanol-powered engines. These E85-compatible fuel injectors are made just for improvements to the INFINITI Q50 3.7L V6. They have CNC-machined bodies, Viton® seals, and pre-calibrated flow rates (650cc/min ±2%) to get the best AFR at boost levels below 2.5 BAR. They can handle 8,000 RPM loads and tremendous heat (220°F), making them great for track builds.
These OEM-spec fuel injectors for 2014–2015 Q50 models are trusted by NASA Racing teams and repair shops. They lower maintenance expenses while still meeting Euro 6 standards.
Products Advantage

Engineered with precision for top performance
Our high-performance fuel injectors are ASNU flow-tested to a ±2% difference, which makes sure that the air-fuel ratio is always balanced, even when the engine is turbocharged (up to 2.5 BAR boost). The 6-hole laser-drilled nozzle cuts down on fuel dribbling by 30% compared to stamped designs. The twin spring mechanism stops injector bounce-back at 8,000+ RPM, which is very important for track-focused INFINITI Q50 builds.
Made to Last in Tough Conditions
These injectors can handle engine bay temperatures of 220°F for long periods of time without breaking down. They have Viton® seals that are resistant to ethanol (compatible with E0-E85 mixtures) and a thermal-shield coating. The OEM-grade EV6/USCAR connectors make it easy to plug and play with 2014–2015 Q50 3.7L V6 models. This cuts installation time in half compared to aftermarket adapters.
Cost-Effectiveness and Personalization
If tuners need specific solutions, our injectors let you change the spray angles (30°–90°) or flow rates (for example, 720cc for Stage 3 kits) for 30 days, and there are no extra costs for minimum orders. The CNC-machined body controls tolerances to within 0.001mm, and factory-direct pricing decreases expenses by 17%, which means that repair shops and fleet operators can save money.

Main application scenarios

Upgrades that make performance faster
Our high-performance fuel injectors are made for people who want to upgrade their 2014–2015 INFINITI Q50 3.7L V6 with aftermarket turbo kits. They can withstand boost pressures up to 2.5 BAR and give a steady flow rate of 650cc/min.
These injectors keep the AFR (Air-Fuel Ratio) steady even at high RPM, which stops detonation and gets the most horsepower out of your engine. This is different from factory injectors, which are more likely to run lean.
They are great for Stage 2 and 3 turbo builds and are utilized a lot in SEMA-awarded Q50 project vehicles. Key benefit: Pre-calibrated latency data that works with UpRev and Cobb Accessport cuts down on tuning time.
Conversions to ethanol flex-fuel
Our ethanol-resistant Viton® seals and laser-optimized spray patterns make sure that our E85-compatible fuel injectors for INFINITI Q50 work well with ethanol mixtures up to E85.
These injectors cut carbon buildup by 40% compared to OEM parts, while keeping flow uniformity within ±2%. This is important because ethanol has a lower energy density.
Perfect for: People who want to convert their cars to E85 without having to give up their regular driving.


Maintenance for fleets and repair shops
Repair chains and fleet operators benefit from no intermediary pricing (bulk orders save 17%) and 48-hour restocking for popular models like the Q50 3.7L.
These injectors fix common problems like cold-start misfires or lean codes (P0171) by fitting directly to the OE, which cuts diagnostic time by 30%.
Restoring old and classic cars
Our OEM-spec direct replacement fuel injectors help keep pre-2010 INFINITI cars original while also making them more reliable.
The EV6/USCAR connector makes it possible to plug and play with original ECUs, so you don't have to make expensive wire changes. These injectors were used in a 2008 G37 restoration that was shown at Carlisle Import Nationals.
They fixed problems with the idle that were prevalent with NLA (No Longer Available) OEM parts.
