ATP blow off valve flanges are the solution to installing a universal
HKS or Greddy BOV on your 08-up STI. ATP blow off flanges are a direct
bolt on to the 08-up 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.
- Notes:
- 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.
- FITMENT:
- Subaru STI 2008-up
