S&B Filters recently posted a video about their new RAM 1500 TRX intake system. In the video, JLT Performance, an S&B company, compares the stock intake with the S&B unit using a typical chassis dynamometer. Not long after the video was posted, fans began blowing up Gale's inbox. "You've gotta see this. They're testing with the hood open!" Having the hood closed during testing is critical in replicating real-world conditions. But in order to close the hood during testing, you must provide ample airflow or the vehicle will overheat. This is where the wheels fall off.

Before the respected 80-year-old engineer had a chance to see the video, we convinced him to watch it on camera. We set up a computer in the race shop and clicked play as the cameras rolled.

Note: Banks has no plans to produce a TRX intake system.
