The 2019 Subaru STI S209 has an intercooler sprayer, here's what it looks like when you activate it

The 2019 Subaru STI S209 gets a lot of features that distinguish it from your average WRX STI including wide body work, a giant wing, additional chassis braces and an extra 31 horsepower. It also brings back a performance gizmo that hasn't been featured in a U.S. market Subaru since 2007: the intercooler sprayer. As the name implies, it sprays cool water onto the air-to-air intercooler when pressing a button. In the case of the S209, that button is one of the paddles on the back of the steering wheel. That triggers the water nozzles hidden in the hood scoop to spray water. You can see what happens in the video below. Note that when the car is in motion, air would carry the spray farther back covering more of the intercooler. Now why would you want an intercooler sprayer? Well, the S209, like all WRX and STI models, uses an air-to-air intercooler to cool off hot air coming from the turbocharger on its way to the intake manifold. The cooler your air, the denser it is, meaning more oxygen to combine with fuel to turn into more power. The effectiveness of the intercooler depends partly on the temperature of the outside air flowing over the intercooler. If it's really hot out, it's not as effective. So spraying water onto the intercooler can counter this to ensure that the car is making maximum horsepower even in toasty conditions. This also means that although this may feel like some special secret performance-boosting weapon, it's really only effective in specific circumstances, and will just get you back to normal power, rather than make the car noticeably faster on the street. Long track days in the summer and after waiting in line at the drag strip or autocross are the kinds of situations where you could see power diminish due to hot air and a lack of moving air. Normal driving won't necessitate its use nor will driving in cool temperatures. In fact, the S209's owner's manual specifically says not to use the sprayer in temperatures below 41 degrees Fahrenheit because of the risk of frozen water in the tank. That brings us to another aspect of the intercooler sprayer: maintenance. In fairness, there isn't much to maintain, but if you want to use the system, you do need to keep the tank filled. It's located in the trunk where the spare tire would normally be. Inside of course is a water pump that connects to hoses that run water to the front. There is a warning light that will illuminate on the instrument panel if it runs low.

The Subaru BRZ tS is back for 2020 — most of it, anyway

We had a feeling the Subaru BRZ tS was coming back not too long ago, and now it’s officially available again for the 2020 model year. This time Subaru is limiting production to 300 units, instead of the 500 we saw built for the 2018 model year. The price is also $1,960 cheaper than the 2018 car, listed for $32,395. That makes it only $650 more than a BRZ in Limited trim. So really, itÂ’s looking a fair bit more attractive than it ever has.  Subaru did take one thing away, though. The 2020 tS eliminated the massive dry carbon adjustable rear wing, replacing it with a shorty spoiler of sorts. WeÂ’re guessing the carbon fiber wing was a rather expensive piece. Everything else carries over, so that means you get the STI-tuned Sachs dampers and springs, STI engine V-brace, draw stiffeners in the chassis and subframe, plus larger Brembo brakes (four-piston in front, two-piston in rear). Michelin Pilot Sport tires wrap 18-inch bronze wheels, and itÂ’s only available in a new Ceramic White paint — the previous tS offered three colors. We also received word of small changes coming to the 2020 WRX and STI. The performance package for the WRX has been massaged a bit, and it adds a big Brembo brake package (as opposed to just high-performance pads) to the list of equipment included. The Recaro buckets, power-driver seat and moonroof delete are still included, but the package costs $2,850 now, versus the $2,050 price for 2019. If an STI is more your flavor, know that it gains keyless entry and push-button start for 2020. Subaru also redesigned the engine bay cooling ducts for better cooling, and added a new dark gray wheel option. The cheapest WRX comes to $28,395 now and the cheapest STI will run you $37,895. Those prices constitute modest bumps of $300 and $400 respectively when compared to the 2019 model year cars.

Subaru BRZ tS makes its brief video debut

Ever since Subaru released the BRZ, fans have been eagerly anticipating the arrival of the STI version. But despite the recent release of the tS package, the brand faithful will have to wait a little longer, because the tS stops short of the full STI treatment. But at least it looks the part.
Though the BRZ tS doesn't encompass any major engine mods to speak of, it does benefit from a number of enhancements: a new driveshaft, aero kit, Brembo brakes, Recaro buckets and more. Which may be more than enough for some, but to tip the scales of disappointment, Subaru will only make 500 such examples, and they'll only be available in Japan. So chances are you won't be getting your hands on one, but at least you can admire it from this brief video clip below. It's not much to go on, but that seems about par for the proverbial course.
