    The APR Intercooler System for the B9 S4/S5 3.0T is now Available!

    Guest-only advertisement. Register or Log In now!


    The APR Intercooler System is a massive front mounted upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! The system is an easy to install, direct bolt-on design, that is recommended at every stage of performance.

    Quick Facts:

    -Dramatically lowers intake air temp (IAT)
    The factory intercooler reaches dangerously high IAT levels, even on the stock ECU!

    -Massive frontal surface area and core volume
    3.125" x 5.75" x 28.25" - 162.4 in frnt. & 507.62 in volume - OEM
    2.250" x 16.2" x 22.00" - 356.4 in frnt. & 801.90 in volume - APR

    -Highly effective core design
    Bar-and-plate core with staggered and louvered fins.
    Rigorous testing determined core style, fin density, and size.
    Low pressure drop + highly effective cooling = high performance!

    -Smooth cast end tanks
    Engineered for low turbulence/restriction and maximum flow.
    Organically shaped to promote airflow across entire core.
    Pressure tested to prevent power robbing boost leaks.

    -Easy to install
    Simple plug-and-play design with no trimming or drilling necessary!
    Designed by engineers with lasers
    With the best equipment and smartest engineers, it just works!




    Testing

    APRs engineers tested each intercooler in a multitude of tests to show the impact the APR intercooler has on intake air temperature. The following tests were conducted with a 2017 S4 using the stock ECU calibration on 93 octane fuel and no other modifications. Ambient conditions during the stock intercooler tests were 72.8F and 98.4 kPa with 78.7% relative humidity. Conditions were similar later in the day during during the APR Intercooler testing with 78.4F and 98.5 KPa with 62.8% relative humidity. This gave the APR Intercooler no added advantage over the stock system during the tests.



    First, six back-to-back dyno pulls were conducted with each intercooler. Each run was conducted in 4th gear, from idle to redline, with a cool down between runs. The stock intercooler failed to combat rising IATs and quickly exhibited power-robbing heat soak. IATs started at 35C and quickly rose to 60C by the end of the first dyno pull. This trend continued with the final dyno pull reaching a staggering 67C! In contrast, the APR Intercooler only reached 34C by the end of the first dyno pull. It was then able to continue rejecting heat, only reaching 36C by the end of the final dyno pull. The APR Intercooler performed better after 6 back-to-back dyno pulls than the factory intercooler did on its very first dyno pull.



    Next we tested a 10-135 second sprint through the gears. With the factory intercooler, IAT quickly rose from a starting temperature of 32C to a blistering 81C! It was so bad, we had to abort the test as we felt it was too dangerous to continue further. However, as expected, the APR intercooler handled IATs extremely well. With a starting temperature of 29C, IAT slightly climbed above the starting temperature to 42C by the end of the sprint. A difference of 39C was exhibited between the two units after only a single top speed. This directly translates to faster acceleration, and better performance in all conditions.

    This is one of the easiest intercooler installs out of any we sell.

    Literally bumper off, swap units, bumper on.

    I know it is probably to early to say but going off the data, will this be a required part for any stage tune? Might as well pick one up now are i await a tune if it is. :)

    I really can't say until we tune the car, but most likely we'll have deep compensation baked in for IAT protection, and benefits when you have the cooler. However if we find it's so extreme it deeply changes with tuning, we may offer two different files - so like a stage 1 and 1+ for use with the cooler.

    Pulling the front bumper is easy. Should be a really strait forward install.

    How does the stock IAT for this engine compare to that of other engines, like the supercharged 3.0 and the 2.0T?

    The 3.0T supercharged engine is atrocious, especially with tuning. The 2.0t I don't recall being that bad without software, but an upgrade helps.

    I've driven one for the past 6 years. The factory cooling is disappointing.

    Just a word of advice: I held off on upgrading the intercooler on my '14 S4 until just recently. During my intercooler install, I realized just how tiny and inadequate the stock intercooler is on the B8.5. Now I'm annoyed with myself for waiting so long to upgrade. IAT's are dramatically improved now, especially when ambient temps climb into the 90's.

    After seeing the dimensions APR posted above of the stock intercooler size for the B9, whether it's an APR unit or from another brand, I highly recommend making an upgraded intercooler an absolute priority for you B9 guys. I'm planning on making the switch to a B9 in the Spring. At which point, this will be my very first mod.

    I just installed an RS-style grille for my B9 S4. For me to install this, I'd have to black it out. What would the airflow/heat exchange ramifications be if I were to spray paint it black?

    I think you'd actually like the way it looks, but if you don't, look into a kephos, which is a phosphorous coating.

    LMAO thanks but I assure you I would most definitely NOT like having a giant silver slab behind my black optic RS-style grille. Talk about defeating the point lol.

    so it sounds like you're saying spray painting it black would have some heat exchange ramifications...

    Any pics with the front bumper on? Is the intercooler easily visible?
