What are our options to stay legal in STU? I've seen the injen and it looks to replace some intercooler pipes which I don't think can be done. Am I stuck with just adding a filter on the end of the MAF?

Are certain intakes more prone to additional peak power. Any that add more low-end/mid range torque?

I'm clueless on intakes for the Evo. Please enlighten me.

 

I ran STU last year. I have the ARC intake box. I beleive anything goes before the turbo air inlet.
