Calling all car modders! Need a durable coupler for your turbo, intercooler, or intake piping? This 90-degree silicone elbow is built tough. The inner diameter is 4 inches (about 102mm), and each leg is about 4 inches long. It's not flimsy – it's made with 4 layers (4-ply) of nylon reinforcement, making the wall about 0.2 inches (5mm) thick. That means it can handle working pressures up to about 85 PSI and crazy temperatures from -76°F all the way up to +500°F (-60°C to +260°C). The silicone is also resistant to ozone, UV, and general wear. It comes with two stainless steel clamps to get a solid, leak-free seal on your pipes. Super important note: This is for air intake systems only – do NOT use it for transferring oil or fuel. Also, because manufacturing has tiny tolerances (about +/- 0.5mm), the fit might be very snug. If you're not super confident with car mods, getting it professionally installed is a good idea. But if you know your way around an engine bay, this is a reliable, universal connector for your project.
