APR Front-Mount Intercooler for Audi RS3 adds almost 30 hp

With a 2.5 liter turbocharged five-cylinder engine, making 400 hp and 354 lb-ft of torque, no one has ever called the Audi RS3 slow. In fact, with a 0-60 mph time of about 3.7 seconds, it’s almost as fast as a Lamborghini Gallardo. So it’s seriously, properly quick. However, there’s always room for a bit of improvement. And APR has designed a simple bolt-on kit for the RS3 that not only increases power itself but significantly increases the potential horsepower and performance in the future.

APR’s new front-mount intercooler kit is a bolt-on unit that instantly reduces the amount of heat in the little turbo five-pot and increases airflow. That alone helps create and additional 26 horsepower. While that isn’t a massive power gain, it’s certainly not a small one. However, that’s not the real point of this APR intercooler. The real reason you get one is for its future power and performance gains.

Without any additional power upgrades, this new cast-aluminum intercooler will help prevent heat soak, which is, in layman’s terms, when the air temperature entering the engine is too hot, which means a lower air density, which means less power. Heat soak is especially common among turbocharged engines that run a lot of boost, like the Audi RS3’s five-cylinder, especially when on the track, where successive laps of hard driving can cause it. A better intercooler will keep temperatures where they should be, allowing the car to keep running hard for much longer.

Also, due to keeping heat in check, APR claims that the Audi RS3 can handle twice its normal power output with this new intercooler. According to APR “Extensive dyno testing was performed during the development process as well. When performing six-consecutive fourth gear dyno runs, the stock intercooler reached intake air temperatures of up to 70 degrees Celsius. In comparison, the APR system reached a maximum IAT of 54 degrees Celsius. The APR system recorded a lower IAT after six dyno runs than the stock system after its first run. While performing a 15 second dyno run through multiple gears, the APR system decreased IAT by 23 degrees Celsius. By dramatically reducing intake air temperatures, the APR Front Mount Intercooler System increases horsepower in a variety of conditions.”

If you’re looking to tune your Audi RS3, this new intercooler will be necessary to keep temps at bay while adding more power. Or even if you’re just looking to track your stock RS3, this new intercooler will keep your engine safe and keep you running hard for longer. Either way, it seems like a worthwhile upgrade for any Audi RS3 owner.
