Hi i have a greddy rs and i wanted to buy the recirculation adapter but they have 4 sizes hmm which one do you think will work with the injen intake cause the biggest opening on the injen pipe is 10mm so i dont know how its gonna fit??

 

well it depends on the hose that your are gonna use to recirculate. And doesnt the injen intake have a spot just for the hose to go on?

 

I have a question along these lines,i am converting my non recirulating injen intake to one that does.With the stock intake,the recirc tube protrudes into the intake a couple of inches.Is that how the injen ones that come to recirc appear also?I dont see the reason why,i was just gonna make a bung on there that was flush mounted and not to protrude into the intake itself,and leave enough on the outside so the tube from the BOV can easily attach.I am just wondering how i should actually mount it,weather protruding into or flush mounted and if it is critical in doing so.Thanks guys

 

it doesnt really even matter either way. As long as you have a good weld on there then your all set.
