The Proof is in the Results! Kozmic Motorsports has gone 8.05 @ 184 using one of our off the shelf units.
Top shelf quality for real. No complaints at all. What sets this company apart from the others is the variety. You can stick to the basic, or customize it way further than the rest. Highly recommend, and my tuner gave me impressive results combined with other bolt ons. 10/10.
Always quality , best intercooler to make Power
Love how the fmic looks on the car. No fitment issues especially with my perrin oil cooler and support bar. One of the best on the market
I’ve purchased multiple front mount inner coolers. Every single one is flawless and up to par! Take a bow, well done guys: as always!! 🤌🏽🤝🏽🏽🔥
Not only does their customer service beat every other company I’ve dealt with, the product is superior to any other. 2nd car I’ve had an ETS FMIC kit on.
One of the best intercoolers I have bought. The quality is awesome. Had to buy the rotated FMIC to go with the rotated turbo kit I bought from ETS. Just wanna say these guys at ETS really do get back at you quick and always answer any questions you have.
QUESTIONS & ANSWERSAsk a Question
How much does a 4 inch weigh
Here are a couple of core weights for your reference
3.0" - 23.5lbs
3.5" - 26.9lbs
4.0" - 30.1lbs
How much Wheel horsepower can the 3.5” support?
We rate these up to around 750whp, but I have a customer in MT who made 822whp through a 3.5" core. We usually leave 10-15% on the table when rating intercoolers as a general rule.
Will this intercooler work with a 2015 wrx?
Yes, the core for the 2015+ WRX and STI are the same, but the intercooler piping will be different.
I am trying to confirm if your 3" core will fit with a Perrin Oil Cooler. I think the hoses from the oil cooler will be an issue. Can you confirm if your front mount will fit?
Hello I have a 2017 STI. Base model I want to buy either a 5 inch or 4.5 inch intercooler but I’m concerned if the fit will not fit my OEM front bumper and if it fits I also have a Varis after market front bumper , could you guys help me
The 4" option we sell will fit. The 5" option requires major cutting and probably won't fit the 17 model bumper cover. It is meant for 18+ bumper covers.
We don't have confirmed fitment on the Varis front bumper cover but based off pictures I think you could fit the 4" or 5" behind that.
What’s the difference between this intercooler and 2015 front mount intercooler ? Are the mount points different ? How about the charge pipe holes ?
All 2015 intercoolers have the same mounting points. 04-07, 08-14 and 15-20 have their own unique design and are not interchangable between model years.
Does the 3.5 inch fit without modification to the front bumper
Behind the fog lights will need to be trimmed to clear the intercooler. Trimming is unnoticeable from the outside.
Will the 4 inch core fit behind the factory 2018 to 2020 bumper without modification?
The bumper cover will need to be trimmed behind the fog light area to clear the intercooler.
What diameter are in the inlet and out let of your cores. Just trying to figure out if I can use my existing piping or not. Thanks.
The inlet/outlets are 2.5" OD.
What's the difference between the 3in an 5in core and when would it be good to upgrade size? What's the power rating of 3in vs 5in. And I'd assume 5in would cause more lagg then 3in
IC lag is not as noticeable as most people think. 5.0" is for full blow racecars. 3.0" is stock turbo cars.
I'm wanting to run apr brake cooling ducts will the 4 inch core clear the ducts?
The intercooler works with factory fog lights. I don't see any reason it won't work with the brake ducts. They look like they take up about the same amount of space.
Do you have any install instructions or a video?
Yes, there is a video on youtube a customer posted.
ETS 15+ Subaru STI FMIC Install
Will your FMIC system fit well with a Cobb SF intake kit on my '19 STI? Also are your headers EL or UEL? The picture looks like EL but I'd like to be sure!
They are EL. It will fit with the intake. But you will not be able to run an airbox. Our intake system will fit without any hang-ups.
If the 5" core only fits w/ an 18+ bumper cover, what is the maximum core size that can fit under a 2015 bumper cover? Or all of the year differentiations for that matter?
15-17 will fit anything under 5.0". It is 5.0" that requires an 18+ bumper
Does the 5 inch core fit on a 2016 Subaru STi?
The 5" core only works if you run an 18+ bumper cover.
Does anodizing make a difference or is it just for looks?
Anodizing is largely a cosmetic modification, it will have little/no impact on performance.
