  • What's the best intercooler, air-to-air or air-to-water? What are the advantages of different types of intercoolers?Why Cold Air Makes more Power - Shirts! - Books & Car Products - for new videos every Wednesday! - engines are trending towards downsized turbocharger solutions. In order to make power efficiently, air temperatures need to be cool before entering the engine. Turbochargers compress air, and doing so increases the air's temperature, decreasing density. That's where intercoolers come in, which use ambient air to reduce the temperature of the air used for combustion. There are two main styles of intercoolers, air-to-air and air-to-water. Both are effective, but they each have their own distinct advantages with regards to packaging, efficiency, turbo lag, throttle response, and of course cost. Check out the video to learn more about how these systems work, and perhaps decide which solution might be best for your own projects!

    Jason said 36 times "cool" and the video is 280 seconds long
    That gives about one "cool" per 7.8 second
    So I can say it is
    a very cool video

    I have a newer BMW with the B58 engine and air-to-water cooler. I was so excited to get it. It performs great, response is awesome, and less to worry about when upgrading.
    Then at 1000 miles i noticed the aux coolant tank that supplies the cooler was dry. Come to find out BMW only put a level sensor in the main tank and not the aux tank. So I had no warning that it was dry outside of a forum thread where several people said they found theirs was empty. So I had my first dealer visit 3 months into ownership.
    Great idea. But it's always going to be a BMW.

    Intercooler on top of the engine. Is that the Subaru Impreza WRX kind of placement?

    An inherently complicated system on top of it being a BMW? Ohh man that thing's gonna be good friends with the dealership service department.

    Yo dawg, I heard you liked cooling stuff, so I used an intercooler to cool your intercooler so you can cool your intercooler while you cool your air

    Thanks for another great explaination video Jason. I've learned so much from your channel and it has helped inspire me to pursue an automotive focus in my mechanical engineering degree. By the way, the whiteboard is legendary.
