The QR's are set up to accept two different types of return fittings - 1" for Bosch style BPV's and 1.34" for DSM and Evo type valves. This is the 1.34" variant.
The spring pressure in the valve does not correlate with the amount of boost pressure you want to run. The size spring you need is determined by your engine vacuum at idle. Please refer to the charge below to select the right pressure for you.

Q: 2012 STi rsubi24 4 years agoAnswer
Does it work fine for a 2012 Subaru STi?
A: This is a universal BOV and will not be a direct replacement for stock. We do not carry any adapters at this time that will allow you to use this with a top mount intercooler.

Q: return hose fitment iforgettopee 4 years agoAnswer
any idea if the 1.34 return fitting will work with the factory 2011-2013 WRX return hose? I understand that this will not be a straight bolt on to the factory TMIC. thanks!
A: That is roughly larger than the stock BPV return hose. The hose may be able to be stretched over it, but the stock hose is probably too small.
