QuestionI recently bough a 09 Impreza, I could not get the WRX because it was a little too expansive. I found a great intake that would add some power to my car, which is not turbo. And I wanted to know if the parts from the WRX would fit onto the Imprza, particularly this intake.
Will this intake fit onto a regular 2.5i Impreza http://wwwiagperformancecom/shopping cart/proddetailphp?prod equals 21-478WR
AnswerPaul,
The link you provided doesn't work, sorry. I will answer about air intakes and intake manifold.
I dont have great news anyways.
There really are zero ways of correctly obtaining horse power increases on a 2009 Impreza N/A engine.
Other than a cold air intake kit(which isn't a great idea all by it self) you don't have much options, other than make the car loader when you accelerate it wont drastically add in more power, if any at all.
Any Manifold change you perform will require a pro tune, and there is no demand for tuning software for the non Turbo engines. Sorry
If you change the intake manifold you will drastically affect the vehicle factory Mapp (air Fuel ratio calculations, fuel trim, spark advance etc.)
