If you're diving into some serious engine work or just looking to upgrade your ride, the HPS 3-1/2" (89mm) x 8" Long High Temp 4-ply Aramid Reinforced Silicone Charge Air Cooler (CAC) Hose Coupler for the hot side is worth a look. I’ve put this piece through its paces, and let me tell you, it’s built to last.

This isn’t just any hose coupler. It’s designed to handle the heat—like, up to 500 degrees Fahrenheit (260 degrees Celsius) hot. Made with a 4-ply aramid reinforcement, it’s tough enough to withstand the rigors of high-performance setups, whether you’re in a custom turbo build or fabricating intercooler piping. Plus, it meets and exceeds SAEJ20 industry standards, so you know you’re getting something reliable.

One of the things I really appreciate about this hose is how it deals with slight misalignments. If your setup isn’t perfectly aligned, this coupler can handle it without skipping a beat. It also isolates vibrations between hose ends, which is a huge plus for keeping everything running smoothly. I’ve used it in both marine and industrial applications, and it holds up exceptionally well against UV and ozone damage, making it versatile for various environments.

Now, let’s talk specs. The inside diameter is 3.5 inches (89mm), while the outside diameter is just under 4 inches at 3.94 inches (100mm). The wall thickness is around 4.5mm, which gives it that sturdy feel without being overly bulky. Just a heads-up, though—this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your setup.

Overall, if you’re looking for a solid, high-temp hose coupler that won’t let you down, the HPS CAC hose is a great choice. It’s reliable, versatile, and built to take the heat, so you can focus on what really matters—getting the most out of your engine.
