Does USDM Evo 9 come with exhaust injection?
Does USDM Evo 9 come with exhaust injection?
I remember reading that the JDM models use wasted and pressurized air before the butterflies to inject into the exhaust manifold creating a rudimentary anti-lag type system that works even better with rear anti-lag. The system is similar to the system used on the corolla WRC cars? DOes anyone know anything more about htis?
