clamped a hose on each (L&R) IC tube. I welded a universal HKS BOV mount to some tubing that fits the OD of the hose, clamped it to each lead from the IC tubes. "T"ed the vac lines that used to run to the stock valves and ran it to the HKS. Then plug the holes to the intake which are no longer in use) So the BOV sits right below the air filter. It works awesome!
