I am planning on buying a Si and was wondering if the FAQs are for all versions of the Civic - including the Si's.

If not, I was wondering what would be the best sound and performance upgrade for my future Si?

As of now, I am leaning towards an AEM v2 SRI; however, I also hear that the Injen CAI is really good as well.

I'm kind of a noob at this so any explanations would be appreciated!

Thanks in advance.

 

performance<sound IMO

i like the AEM better
