**Currently we are out of this intercooler core. Build time is roughly 5-6 weeks.**


Tired of heat soak? We don't blame you!  

It's time to upgrade to an intercooler that is designed specifically for the 2015+ STI with performance in mind.   Unlike other manufacturers, we design all of our cores per application, which results in the absolute best performing intercooler on the market.

All of our cores feature an offset and staggered internal and external fin pack.   The external fin pack is dense for maximum heat transfer, where the internal fin pack is less dense for maximum flow and performance.   The key is finding the perfect balance between the two, which is what we do per application.    

It's common for customers to be drawn to cheaper alternatives.   Unfortunately, those intercoolers are cheap for a reason!   Most cheap intercoolers utilize a straight-through internal fin pack, which acts more like a tunnel than a splitter; This result is much higher/hotter intake air temps, which then leads to timing reduction, knock, misfires, detonation, etc.

The ETS 2015+ STI Intercooler is designed to perform!  

  • We start by locating the inlets and outlets in the middle of the core, which allows for proper air distribution and flows throughout the core.  
  • Each inlet and outlet are hands ported to reduce turbulence and promote maximum flow.   We've seen other manufacturers simply weld on a tube and not deburr the inside, which creates excess turbulence and disrupts airflow through the core.

    • If I add an aftermarket BOV do I need to add the AIT Bung?

      The AIT Bung is for a sensor needed to run Speed Density. If you are running the Stock MAF you won't need this.

    • hi can you tell me what's the shipping weight of this item please, thanks

      Shipping weight should be between 45-50lbs.

    • How can I get red pipes instead of the crinkle black?

      Unfortunately we do not have an option for red pipes at this time.  We can send the pipes to you in raw stainless steel and you can have a local powder coater coat them.  If you would like to proceed with this option please note in the comments that you would like the pipes to be raw finish.  Thank you!

    • Does the rotated intercooler piping work with a stock intake manifold for a wrx sti 2018 ?

      Yes it does!

    • Will this kit fit a fp blue turbocharger ?

      Yes, just select the stock replacement turbo option.

    • I have the turbo smart dual port BOV on my 2016 wrx and I bought the fmic from you all. Will I have any problems with it fitting?

      Yes, just make sure you select the stock BOV flange. The dual port uses a stock BOV flange.

    • Will your 2015 STi Front mount kit fit with the Cobb SF intake & SF intake Box?

      It does not work with the box unfortunately
