If you're looking to upgrade your charge air system, the HPS 3" (76mm) x 12" Long High Temp 4-ply Aramid Reinforced Silicone Charge Air Cooler (CAC) Hose Coupler for the hot side is a solid choice. I’ve had my hands on this piece, and I can tell you, it’s built to last. This isn’t just any silicone hose; it’s engineered to handle the heat and pressure that come with a performance engine.
First off, let’s talk about the construction. This hose is made with a 4-ply aramid reinforced silicone, which means it’s tough enough to take on temperatures ranging from -65°F to a scorching 500°F (that’s about 260°C for those who prefer metric). That’s crucial if you're pushing your engine hard, whether on the road or at the track. The wall thickness is about 4.5mm, which adds to its durability without being overly bulky.
One of the standout features is its ability to handle slight misalignments. If you’ve ever tried to fit hoses in tight spaces, you know how important that is. This hose does a great job isolating vibrations between hose ends, which helps keep everything running smoothly. Plus, it’s UV and ozone resistant, so it can withstand the elements if you’re using it in marine or industrial applications.
Now, about the size: it has a 3" inside diameter (76mm) and an outside diameter of 3.39" (86mm), making it a versatile option for custom turbo setups or intercooler piping fabrication. The length of 12" gives you enough room to work with, whether you’re making adjustments or just need a little extra reach.
Just a heads up, though—this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your setup. But if you’re looking for a reliable, high-performance hose that meets and exceeds SAEJ20 industry standards, this HPS CAC hose is definitely worth considering.
