The JEWELZ System PN 232-808

We named this the Jewlez because it’s what is underneath the intake that counts. This hidden gem is the key to performance when adding a second or third system to your manifold when space is crucial.  Let the Speedtech team of technicians install this one, we actually machine a new belly plate in the manifold floor that is removable for quick access to the nozzle jetting arrangement.
