Way better than stock intercooler!!

Drop temperatures to 15-30*f cooler then stock intercooler, double width than stock core as well. Perfect fit

Seems ok

The "intercooler" I received was packaged extremely well, but it barely had any "bead" around the "hose clamp" areas, also had a few dings and bent fins.

I had some trouble getting the stock charge pipe to hold any more than 10 psi of boost before popping off no matter how I installed the cooler. lucky for me I ordered the Perrin Charge Pipe when I ordered this TurboXS Intercooler... unlucky for me, I ran out of daylight today so I will have to install and try the Perrin pipe tomorrow.

Test drive went good as long as I didn't go boost heavy, on one back and forth test driving "normally" I seem to be using about 6% less throttle when I went on my normal route fighting heavy head winds and a few hills hear and there. Don't know where all the heat goes in this thing, after a 20 minute test drive while trying to hold positive boost both "Hot" and "Cold" sides of the intercooler was ice cold to the touch, engine oil temps barely touched 201 F when they would usually be upwards of 207 F during a similar drive.

When I fist bought the car it would see oil temps upwards of 221 F doing this same drive but I helped a few things along the way; Lubegard "Liquid Wax Esters" engine oil and differential oil additive at 3oz Lubegard per quart of oil, 0w30 Euro Spec full synthetic oil, Mobil 1 gear oil, "bumper, headlight, and hood aero mods", and an AEM air intake helped get the car down to 207 F, so far a free flowing "intercooler" seems to help keep the oil temps down another 6 F during my "keep on the boost" test drive, and I normally drive using boost only when needed

Installed on a 2017 Subaru with the FA20 DIT engine... I recommend you get an aftermarket charge pipe to get the extra few inches worth of silicone biting down on the TubroXS "Intercooler"... now is also a good time to upgrade the hose clamps :)

Taking away 1 star for the lack of "hose clamp bead" and the few dings/dents... for $600 of someone's hard earned $$ the thing should look immaculate if y...

TMIC upgrade for my 14 FXT

This was the final addition to my stage 2 mod list before my FXT was retuned. It was the missing link, pulling everything together, it made an incredible impact over the stock TMIC; really brought the charge pipe, TBE, TGV deletes to life. Shipping was fast and the piece was at a price I couldn't pass up, would have been such a weaker tune if I hadn't.

Great Price, Power and Easy to Install

First time upgrading an intercooler and was a very simple straight forward upgrade. Paired this with my AEM Charge Pipe and really seems to make a difference on how quickly the turbo spools and keeps temps much cooler than factory TMIC (Can't wait to get the car in for a pro tune to really take advantage!). This was also my first transaction with MAPerformance and definitely won't be my last! Hope their inventory for the 2015 WRX keeps growing because they always seem to have not only the lowest available price but also are usually offering a discount code...sometimes up to an extra 10% off...#Unbeatable!!!!
