last time we use hks airfilter felt more powerful than blizt sonic power,
but final we change back the stock air-filter,the rpm fast rev,and the sound for engine rev no nice.
This is my Bro's car SV4,
need to leave it and i try to text at last,
i felt so good for the 2.2cc and AT gearbox for this engine
What Ecu and Tcu are you using?.
