For Acura Integra enthusiasts looking to boost their engine’s performance, upgrading your fuel injectors is a crucial step. Whether you’re aiming for increased horsepower, improved throttle response, or preparing for forced induction, the 550cc High Quality Fuel Injectors by KSM Motorsports offer a reliable and effective solution. These injectors are specifically designed to be compatible with a wide range of Honda and Acura vehicles, including various Acura Integra models, and are an excellent choice for OBD2 systems and beyond. ECU tuning is generally required to properly utilize these higher flow injectors and maximize your engine’s potential.
Why Upgrade Your Integra Fuel Injectors?
Stock fuel injectors are designed to meet the fuel demands of an engine at factory settings. However, when you start modifying your engine for more power – such as adding a turbocharger, supercharger, or even performing significant naturally aspirated upgrades – the original injectors may become a bottleneck. Upgrading to higher flow injectors like these 550cc units ensures your engine receives the necessary fuel to support increased power output. This is particularly important for Acura Integra models, popular platforms for performance modifications. Moreover, performance injectors can offer improved fuel atomization, leading to more efficient combustion and potentially better MPG under normal driving conditions, alongside enhanced performance when you demand it.
KSM Motorsports 550cc Injectors: Precision and Performance
These fuel injectors from KSM Motorsports are engineered for both performance and reliability. Each set of injectors undergoes rigorous testing and flow matching to guarantee consistent flow rates across all four injectors. This precise matching is crucial for balanced cylinder fueling, preventing lean or rich conditions that can harm engine performance and longevity.
Flow-Matched and Tested for Quality
KSM Motorsports takes quality control seriously. Each injector is individually tested to confirm its flow rate, ensuring that you receive a set that performs consistently. This flow matching process eliminates guesswork and ensures optimal engine performance after installation and tuning.
Superior Fuel Atomization
The design of these injectors focuses on delivering superior fuel atomization. The multi-hole disc nozzle is designed to create a fine mist of fuel, which mixes more effectively with air. This improved atomization leads to more complete combustion, resulting in better throttle response, increased power, and potentially improved fuel efficiency compared to injectors with poor atomization.

Installation and Tuning Considerations
While these injectors are designed for straightforward installation, there are a few key considerations. For some older models (1986-1991 Acura Integra, 1988-1997 Honda Accord, 2001-2002 Honda Civic, 1992-1996 Honda Prelude), you will need to remove the OEM resistor box. For many later models, particularly those from 1996 onwards, you may require connector clips (EV1 clips), which are available free of charge upon request when you make a purchase – simply add a note at checkout.
Crucially, upgrading to 550cc injectors will necessitate ECU tuning. The increased fuel flow requires adjustments to your engine’s fuel maps to ensure optimal air-fuel ratios and prevent running too rich. Proper tuning is essential to realize the full performance benefits of these injectors and maintain engine health. Professional ECU tuning is highly recommended after installation.
