I have a 2.2L and I don't really think I want better performance anymore. I'm going for styling and fuel economy.

So, I'm planning to get the LSJ DP and Cat-Back. To go with it, I want to do something with the intake to get more mileage.

Which of these choices will get me the best fuel economy?

*K&N Drop In with Intake Mod

*CAI (Injen most likely)

*WAI (GMPP or K&N)

I want to get the best increase in economy and wouldn't mind the little bit of performance to go with it.

Obviously the drop in is the cheapest, but will I see an improvement like I would with one of the other two?

 

To be honest, I don't think any of them is perse going to be hugely better than the other. The major benefit of going with a WAI/CAI/FWI is the new piping which should smooth out airflow and be better. Minus that fact in the end they are all high flow filters and should work basically the same.

The only reservation is FWI in the winter the air might get too cold and cause less mileage because of it.
