We have been getting quite a few inquiries from clubcivic customers about whether or not the Synapse Synchronic Blow-Off Valve has an adapter flange for users that already have a Tial 50mm flange welded on the intercooler piping. We have just completed production of these flanges. The new part number is SB001.6A and allows you to bolt the Synchronic BOV as a direct replacement for the Tial 50mm BOV. This is in addition to the HKS SSQ and Greddy Type-S/R/RS flanges that are already in production.
