My 1999 996 came to me with a Evolution Motor Sports High Flow Fresh Air intake sytem. I am looking to find someone who would want to exchange their stock airbox for this highflow system. My two cents is that under normal conditons i would be better off with the stock intake system.

I'm curious why that is, several people here seem to like that intake. Are you having problems with it?

 

My check engine light was on and when i went to the dealership in their opinion might be causing the problem. I don't track the car and wanted to put it into its original condition. I agree for the most part The high flow system has received great reviews.
