Intake for hybrid

[Kato4276]

I am going with a RAW Performance Street series 2.5L short block along w/ my EJ20 heads. I will bw running a VF39 and STi TMIC for now. As for fuel I have the standard 255 lph fuel pump and the injectrs are modded WRX injectors. My tuning is done via a EcuTek tune. My question is will a 70 mm APS intake work ok or is the 65 mm better. I have a chance to get a 70 mm fairly cheap so was curious.

You will have to retune for the 70mm intake and I doubt you will see any real gains from it over the 65mm.Especially using the VF39 and USDM STi TMIC.The stock airbox would even still work just fine with that setup with a high flow panel filter and 3" velocity stack crammed in the air inlet hole from the fender.
