Product Information

Cleaned and ported, these manifolds will help your FWD 3.1 engine breath.  Gasket matched and blended for a smooth transition from the upper intake to the lower and finally to the head.  The ports are left with a rough texture for better flow and air/fuel mixture quality (or a wet shot of nitrous).  Larger TB opening option is for a 56mm TB.  If you are going larger, please select >56 and tell us the size.  You may be required to send your throttle body to properly match the intake to it.  $80 refundable core charge is applied if you are not sending a set of manifolds in first to be ported.
