Add power to your 997 GT3/Cup 3.6/3.8/4.0L  Our tuned length intake runners push the power!  The 93mm or optional 102mm Throttle body (102mm requires motec or other standalone ecu) allow low resistance to flow.


On our 3.8L test car we increased the power from 400whp with race headers alone to 440whp with race headers.


We recommend a high quality header (like our race or catted header) that moves peak power to 8300-8500rpm


* Fueling and igntion MUST be tuned with this part.
