Audi 7A EFI Injector Adapter Kit for B3 Audi 80/90/Coupe Quattro I5 20V - IMPROVED
Wake up that sluggish 20v!
This chipset is a direct upgrade for the stock 7A engine. Substantial power gains in the midrange make for a much broader powerband.
We have software for both the early (2 connector) and the later (4-connector) ECU. Select your ECU type above before checkout.
Note: We now only ship chips which can be installed by the user or an ECU specialist, we no longer offer the service of shipping in ECU's and modifying them.
**Not for use on emissions controlled vehicles in California, off road, track, and racing applications only**
