I have an injen intake coming for my 2011 sti. And just wondering if anyone has one on there sti. Or wrx? And do u like it? Was it easy to install?
The piping is what causes the problems. If the airflow is different from stock (i.e. different velocity stack, piping diameter, etc.) you will need to re-calibrate your MAF tables.i just put an injen on my car. havent really noticed a difference, but only owned it for a day before putting the intake on so not sure...its a short ram with a Spectre filter on it. just the pipe is injen
