I bought my AEM regulator from a Summit Racing's Retail store for like 169 or somethin.. i'm sure u could find it cheeper on the net if u have the time to shop around & what not.. also some of the autoparts stores that carry any other AEM products should be able to order it for u.. u just have to find the right person to talk to i guess. good luck on that.. (sry i didn't realize that the B & M regulator wasn't a complete regulator replacement like the AEM -good catch CivicRacr-)
