Hi All,

Just wondering if anyone out here might know why one STi Intercooler has the plastic Y pipes vs a solid piece Y pipe

Heres some pictures

Thanks

 

STIs dont come with plastic Y pipes, only cast aluminum, like in the top left. the one in the bottom pic is the stock WRX plastic Y pipe, the Y pipe on the right is a Samco hose, you can even say it says Samco in the pic, niether the STI or the WRX come with this stock. Hope Im understanding your question correctly

 

thats pretty much what I was trying to find out...

 

Better to convert an 04 to an 05 Y-Pipe???

 

no, they are the same

 

I just installed the Intercooler. Even with the STi "Y" pipe it seems to just be a TAD short (if I were to align and bolt the intercooler onto the stock mounting bracket). I can make it fit without extending the pipe if I don't mount the intercooler to the bracket and just let it rest on top, but that'll make it rattle.

Also, I notice that the center hose (that connects to the throttle body) could be a bit short.

The STi Intercooler didn't come with the BOV gasket, so I re-used the existing one from my stock one. Is that ok? The reason I ask this is because the stock one is spot glued onto the stock IC. Is that to just hold it in place or is that required?

Thanks

 

okay wait a minute, are you saying you have a WRX and are trying to install an STI intercooler? if so then yeah it mont fit without a longer throttle body hose. I woulda told you that

 

I kinda got it to fit in a way that the hose will just clamp the throttle body - but it looks like i'mgonna need to invest in a set of samco hoses... Is that generally the way everyone is approaching this?

 

SO
Do most people get a set of samco's? They have a longer throttle body/IC hose?

Thanks
