COBB Tuning is announcing a restructuring of the AccessPORT product line in order to better align our internal resources with our core markets. Effective immediately, COBB Tuning is discontinuing development of AccessPORTs for the Honda Civic Si. Other naturally aspirated platforms affected by this restructuring include the Infiniti G35 & G37, Mazda RX-8, Nissan 350Z & 370Z and Subaru 2.5i & 2.5RS.




From the makers of the GO-Power KSi cams, comes the answer to your exhaustion woes: 3" of stainless-steeled, mandrel bent, tig-welded, and tastefully-embossed GO-Power exhaust power. This is the next addition to your build. Making at least 4whp/5lbs tq, usually more, throughout the rev range on an N/A KSi Civic Si.
