Description

Link ECU Ballast Resistor Set of 4 For Use w/ Low Impedance Injectors | Fuel System Optimization | Engine Management

Overview

The Link ECU Ballast Resistor Set of 4 is a specialized solution designed for Subaru owners who are upgrading their fuel injection systems with low-impedance injectors. This set ensures a stable and consistent current flow to your injectors, which is critical for precise fuel delivery and optimal engine performance. Whether you’re tuning your Subaru WRX, STI, BRZ, or other models, these resistors help protect your ECU from potential damage caused by high injector demands, providing peace of mind during high-performance modifications.

Built with quality and durability in mind, the Link ECU ballast resistors are engineered to meet the demands of Subaru enthusiasts focused on tuning and reliability. Each resistor features a 4.7-ohm, 25-watt rating mounted on a robust heatsink, which efficiently dissipates heat during extended high-duty cycles. This thoughtful design ensures longevity and consistent performance, even under demanding driving conditions. Proper chassis mounting of the heatsink is recommended to maintain optimal temperature and extend component lifespan.

For Subaru owners pushing their vehicles for more power and better fuel management, this resistor set is an essential upgrade. It allows for safe operation with low-impedance injectors (below 2 ohms), enabling advanced tuning capabilities without risking ECU damage. Compatible with a range of Subaru models, including the WRX, STI, BRZ/86, and others, this set provides a reliable foundation for your fuel system upgrades and tuning projects.
