Overview The Bosch 0280158040 is a proven 980cc high-impedance injector that's become the go-to choice for serious turbo builds and high-output naturally aspirated engines. Flow-matched in sets by our RED programme, these injectors deliver the precise fuel delivery needed for 600+ horsepower applications whilst maintaining excellent idle quality and part-throttle drivability. Technical Specifications Part Number: HT-080100RED OEM Number: 0280158040 Flow Rate: 980cc/min at 3 bar Impedance: High (12+ ohms) Fuel Compatibility: Petrol, E85, methanol Spray Pattern: Single cone Connection: EV1 (Jetronic) plug Flow Matching: ±2% variance within set Why You Need This When you're pushing serious power, OEM injectors become the bottleneck. The Bosch 0280158040 solves this with nearly double the flow capacity of most factory units, making it perfect for big turbo 2JZ builds, high-boost SR20DET setups, or naturally aspirated LS engines with aggressive cam profiles. The high-impedance design means direct compatibility with your Haltech ECU's injector drivers — no need for resistor boxes or additional electronics that can introduce failure points. Our RED flow-matching programme ensures each set varies by less than 2%, critical for smooth idle and consistent AFRs across all cylinders. We've seen too many builds suffer from rough idle and uneven cylinder temperatures because of poorly matched injectors. Whether you're building a street-driven Skyline GT-R or a track-focused S-chassis, these injectors provide the headroom and reliability your tune demands, with excellent atomisation characteristics that work brilliantly with E85 fuel systems. ECU & System Compatibility Direct plug-and-play with all Haltech Elite and Nexus ECUs. The high-impedance design works perfectly with the injector drivers in Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 systems without additional hardware. Your tuner will appreciate the linear flow characteristics and excellent dead time consistency across the operating range. What's in the Box Bosch 980cc fuel injector (0280158040) Flow-matching certificate (RED programme) Individual flow test data Complete Your Build Most customers upgrading to 980cc injectors are also planning fuel system upgrades — we stock high-flow fuel pumps, upgraded fuel rails, and pressure regulators to match. Our technical team can spec the complete fuel system for your power target and help avoid the common mistake of upgrading injectors without addressing fuel delivery.
