decrease it? what about MPG? will the airflow increase that by a little bit?

 

long story short... our stock airbox is ok even with 450hp )) It is really good designed.
I think Carbonio intake from APR might give you about 2-3 hp but it is around $400.

 

Engines are tranny specific. Meaning manual tranny wont bolt right up to an engine that you removed an auto tranny from. I have heard that there is a shim or plate adapter that can be used though. Thats all i know about it. Also if there is no auto tranny for the TCU to communicate with, you'll have a fault, and you'd probably need an ECU from a manual car too.

It's called level10 upgrade. If you are at all interested in it, do a lot of research. Or I can save you the time by simply asking if you want your car to shift like a school bus...?

Not to mention mingling in the clutch hydrolics and electronics.... Sell your car and get a manual.
