The GR Corolla goes under the knife for one of the most satisfying power adders - Flex Fuel. The ease of install and power potential when a car is properly setup for flex fuel is hard to beat. We have the world's first plug and play kit for the GR cars on the OEM ECU paired with EcuTek custom tuning!

Enjoy - and if we can help you with tuning or parts, don't hesitate to visit our site or get in touch!
