08-10 STI ATP Universal BOV Flanges
ATP blow off valve flanges are the solution to installing a universal HKS or Greddy BOV on your 08-10 STI. ATP blow off flanges are a direct bolt on to the 08-10 STI top mount intercooler, or front mount intercooler utilizing the same flange. This setup will only vent to the atmosphere. Recirculation set up is available only if you purchase the Greddy specific kit.
The ATP recirculation plug is used when you convert from a recirculating system to a fully venting system. This plug is installed into the stock recirculation hose to prevent vacuum leak.
- These flanges are only necessary when adapting a universal valve to your STI.
- These flanges will set up your car for a venting (VTA) bov only and do no include hardware/fittings required for a recirculating system.
- These are flanges only, blow off valves are sold separately.
