Nice upgrade


Process west tmic 2013 sti hatchback
2 years ago
This intercoller is great. Had a process west that was designed for a 03-05 sti, but modified it to work on my car. Up until janurary of this year got tired of having the wrong one on my car. So as a result i listed the old one on ebay and brought the proper one in the black finish. Love it, very well made, kind of on the heavy side but my iat's are very good and the fitment is next to none. Would recommend this product to anyone who doesn't want to go for a fminc like myself. Also can't complain that this unit will support up to 500 awhp which may be in my cars future someday. As for the other mods, car has bigger injectors, cold air intake, electronic boost contoller, and a cobb v3 tuner. Car was protuned by turbotec tuning in albany ny, and on e-85 it made 350awhp and 400 ft pounds of on torque on a safe tune. On 93 octane it made 320hp 350tq. Overall great upgrade over the stock intercooler.

Great intercooler and great fitment. Full bolt ons, Full fuel system on e85, and cobb 20g all on stock block pushing 445whp and 444trq. Will be building block and head soon. Going to go rotated with either a p&l 30r or 35r shooting for 550-600whp while keeping the pw tmic and see how it can stand up to the power. I'll keep you all posted when it happens.


Quality Intercooler
eod13x 3 years ago
If you are looking to keep living the TMIC life, this intercooler will not disappoint. The quality is top notch, I like that the fins are recessed a bit to help prevent them from folding over from rubbing on things or getting bent. This is way more awesome than the factory intercooler. An unfortunate pressure washing incident (never let your overzealous friends with new pressure washers wash your car) had me spending hours of my life and doing irreparable damage to my lower back bent over my car straightening out my factory cooling fins with a small flat tipped screwdriver. The back side is all tubular (unlike the factory weird oval crap). I'm no fluid dynamics major, but I can bet the flow rate is vastly improved over factory. The only one tiny nit picky complaint I have is that they could have threaded the bolt holes on the BOV port about 5mm deeper to fit a wider variety of aftermarket BOVs. I was able to get my GFB Respons hybrid to fit, but I felt like I was cutting new threads inside there with the bolts for the last few turns. Other than that, fantastic product. The guys at my local shop say they have tuned cars with this intercooler and other supporting mods into the 400's on wHP and wTq. So if you want to make good power but still want to be living the TMIC life, this is a great option.

Love this intercooler

    Hello, Im wondering how I would go about installing this tmic, I have a Crawford tmic aos and how would I install this with the way this aos is setup. thank you

    • A: This will be just like a standard install of any intercooler. Nothing really changes but size. So there should be no issues with your AOS as long as it is top mount as well.
