Key Features: 100% silicone with heat - resistant fibers, quick installation (under an hour), direct fit, increased pressure tolerance, multiple color options, reuses stock hardware, and a lifetime warranty.

Using the Mishimoto silicone throttle body hose is straightforward. First, locate the old throttle body hose on your Subaru WRX, Legacy GT, or Forester XT. Remove the stock hardware carefully and take out the old hose. Align the new Mishimoto hose using the position indicator and put it in place. Then, reuse the stock hardware to secure it. It should take less than an hour to complete the installation. As for maintenance, check the hose regularly for any signs of wear or damage. Since it can handle high temperatures up to 330F (166C), it's quite durable, but it's still a good idea to keep an eye on it. If you notice any cracks or leaks, contact Mishimoto as the hose comes with a lifetime warranty. Also, make sure the hose is not exposed to sharp objects that could puncture it.
