With the mods listed below what would one think of adding a STI top mount intercooler? Would a gain be noticeable? And if so how much would we be talking? Unfortunately all I have ever modded is mustangs and it feels like I am starting all over again. hnoes: Thanks!!
the sti top mount is quite a bit less restrictive than the wrx one. many people are happy with this up grade. but sometimes you can find aftermarket ones for sale just as cheap. also if you get the sti tmic make sure it comes with the y piping cause the wrx y pipe doesnt fit the sti tmic.
You'll get some gains, and greater gains if you tune for it. Not a bad upgrade if you can find a good deal.
STi intercooler has good cooling capacity... however, it has a larger pressure drop compared to a bar and plate IC like the hyperflow
