Intercooler.
 

2013 WRX. Daily driver. What's the best inter cooler? I am only interested in doing a top mount. I'm thinking between Perrin or AVO. Any suggestions? Would you do a turbo back exhaust first ? Definitely a price difference . All opinions welcome. Thanks

Stock turbo = stock intercooler
I have DD WRX and the only thing I've changed performance wise is turbo back.. And tune of course

I wouldn't worry too much about it, save your money for a tune

So far I did a cold air, strut tower bar, bpv, and a custom tune on my Cobb access port. I really have my mind set on doing both but unsure which to do first. I was looking at one by grimmspeed also.

If you really want 1 Process West has the cleanest design

If you plan to get a tune and run more than stock boost, get aftermarket. The ends of the stock Intercooler tend to leak. Perrin is great for the price
