If you're looking to get the most out of your S197 Ford Mustang, you’ve got to check out the HPS FOH hose. This isn’t just any old adapter hose; it’s specifically designed to bridge the gap between standard round tubing and your oval throttle body. I’ve used this piece on my own Mustang, and let me tell you, the fitment is spot on. The pre-formed shape means you won’t be wrestling with awkward transitions—just a smooth connection that feels right.
What sets this hose apart is its construction. Made from a tough, race-proven silicone material, it’s reinforced with 4-ply polyester, so it can handle some serious heat—up to 350 degrees Fahrenheit, to be exact. Whether you’re running a naturally aspirated setup, a supercharger, or even a turbo, this hose has got your back. It’s perfect for connecting your intake or intercooler tubing to that twin blade throttle body. The overall length is 3.5 inches, which keeps things tidy and efficient.
In terms of specs, you’re looking at a silicone oval to round coupler in a sharp blue color. It’s designed specifically for the Ford 55mm throttle body (M-9926-MGT) and connects to 3-1/4 inch tubing. If you want to make sure your Mustang breathes easy and performs at its best, this HPS Performance hose is definitely worth considering.
