EVO Performance Audi RS3 / TTRS / RSQ3 2.5 TFSI Port Injection Kit

Description

This Port Injection Kit is designed for Audi 2.5 TFSI engines to provide additional fuel delivery beyond the limitations of the factory direct injection system. It is commonly used in high-performance builds where increased fuel demand is required, such as upgraded turbochargers, high boost applications and ethanol fuel setups (E85).

The system adds a supplementary port fuel injection solution by integrating additional injectors into the intake system. This ensures improved fuel distribution across all cylinders and allows the engine to maintain stable air-fuel ratios under high load conditions.

The kit typically includes a fuel rail, injector mounting solution and fuel line components designed to handle increased fuel flow. By supporting higher fuel volume, the system enables safer operation at higher power levels and helps prevent fuel starvation under aggressive tuning conditions.

This type of upgrade is essential for high horsepower builds where the factory high-pressure fuel system alone is not sufficient. It is commonly used in conjunction with ECU tuning, upgraded fuel pumps and ethanol blends to achieve maximum performance.
