BLOX Racing Eco-Fi Street Injectors 550cc/min w/1/2in Adapter Honda B/D/H Series (Set of 4)

BLOX Racing has built a strong following in the import and sport compact community since 2003 by delivering parts that meet or exceed OEM quality standards at prices that make building accessible. Every BLOX product is designed with ISO 9001-certified manufacturing processes and subjected to rigorous testing before release, ensuring fitment and reliability that matches the performance they advertise. Popular Upgrades BLOX Racing intake manifolds and throttle bodies are popular for Honda, Acura, and other sport compact platforms, delivering improved airflow and throttle response over stock components. Suspension components including adjustable end links, sway bars, and pillow ball mounts allow precise handling tuning for street and autocross use. Engine hardware — cam gears, valve train components, and timing chain kits — rounds out the BLOX catalog for builders pushing beyond stock engine parameters. What platforms does BLOX Racing support? BLOX Racing focuses primarily on Honda, Ac...

This engine parts collection covers oil catch cans, thermostats, thermostat housings, radiator components, coolant accessories, engine covers, fuse box covers, cap covers, throttle bodies, supercharger pulleys, idler pulleys, tensioner pulleys, and engine bay dress-up parts for trucks, SUVs, muscle cars, boosted builds, high-horsepower street cars, and performance vehicles that need better reliability, cooling, airflow, oil control, and under-hood styling. The collection is particularly strong for Dodge Challenger, Charger, Durango, Jeep Grand Cherokee Trackhawk, and Ram TRX platforms running 6.2L Hellcat, 6.4L HEMI, and 5.7L HEMI engines, where oil catch can and cooling upgrades address known OEM weaknesses in the PCV and thermal management systems. Import performance platforms including GM LS-based builds, Chevrolet Camaro, and Corvette applications are also represented through Mishimoto, CSF, and ZPE GripTec product lines. Builders who invest in engine bay organization and reliab...

Fuel injector connectors are the electrical interface between the engine wiring harness and each individual fuel injector solenoid, carrying the precision pulse-width-modulated signal from the ECU that controls injection timing and duration. Connector failure, corrosion, or poor terminal contact causes intermittent misfires, rough idle, and lean conditions that are frustratingly difficult to diagnose without testing each injector circuit individually. Replacing damaged or corroded injector connectors with new pigtail harnesses using factory-grade terminals restores clean electrical contact and eliminates ghost faults that confound standard scan tool diagnostics. Builders doing engine swaps or injector upgrades also rely on connector pigtails to adapt factory harnesses to new injector styles without permanently altering the original wiring. Popular Upgrades Top-selling injector connectors include Delphi and Bosch OEM-spec EV6 connector pigtails for late-model GM, Ford, and Chrysler E...

Fuel injectors are the precision metering devices at the heart of every modern electronic fuel injection system, responsible for atomizing fuel into a fine mist at exactly the right moment, duration, and spray angle for complete combustion. As injectors age, internal deposits and solenoid wear cause flow rate deviation, tip coking, and spray pattern degradation that result in rich or lean cylinder conditions, rough idle, elevated emissions, and reduced fuel economy. Selecting the correct replacement or performance injector requires matching the flow rate, impedance, connector type, and spray angle to your specific engine and fuel system configuration. From factory-replacement units restoring a daily driver to high-impedance Injector Dynamics sets supporting four-figure horsepower builds, this collection covers the full range of fuel injector needs. Popular Upgrades Top-selling fuel injectors include Bosch OEM-replacement and remanufactured injectors for high-volume domestic and impo...

Purchasing a single fuel injector is the right approach when diagnosing and replacing a confirmed failed unit in an otherwise healthy set, or when building a custom EFI system that requires individual injector placement in a fabricated intake manifold or throttle body. A single injector replacement is commonly performed after a misfire diagnosis isolates one cylinder's injector as the root cause, avoiding the cost of a complete set replacement when only one unit has failed. For custom EFI builds using individual throttle bodies or single-point injection conversions, sourcing matched single injectors allows precise flow-rate targeting per cylinder independently. Whether repairing a daily driver or building a custom engine, having access to individual injectors at the correct flow rate and connector spec is essential. Popular Upgrades Top-selling single fuel injectors include Bosch OEM-replacement EV6 units for late-model domestic and import EFI applications, Siemens Deka 60-pound and...
