VAG 2.0TFSI EA113 RS3 Injector Kit (up to 500hp)

Bar-Tek RS3 injector kit for EA113 2.0 TFSI engines, up to 500 hp

The Bar-Tek RS3 Injector Kit is a proven fueling upgrade for EA113 2.0 TFSI engines when aiming for around 500 hp and the stock S3 injectors become a limitation. This kit includes 4 injectors that have been flow tested and perfectly matched, plus the required adapter plugs, making it a ready-to-install solution for serious builds.

• Complete set of 4 RS3 injectors for EA113 2.0 TFSI
• Approx. 20 percent more flow than OEM S3 injectors
• Optimized spray pattern for TFSI combustion chambers
• Injectors are tested and matched as a set
• Includes matching adapter plugs and wiring

What does it do

When increasing power, fueling capacity is often one of the first limiting factors. RS3-style injectors increase fuel delivery and help maintain proper AFR and safe EGT levels under high load. The key benefit of this kit is the correct spray pattern for EA113 applications, supporting clean and stable combustion.

Important note

Installation may require RS3 cylinder head style injector depth. In some cases machining of the head or valve area is needed to position the injector correctly into the combustion chamber. Professional installation and ECU calibration are strongly recommended.
