Air Duct Tubing | RCP HSBD4SIL

When you’re pushing hard, heat is the enemy. This high-temp silicone brake ducting is built to move serious air where it matters most - straight to your brakes.

Perfect for track cars, drift builds, or any setup where braking performance needs to stay consistent under pressure. The 4-inch diameter gives you solid airflow, while the flexible silicone construction makes routing easy, even in tight engine bays or wheel wells.

Designed to handle high temperatures without collapsing or degrading, so you can focus on driving, not worrying about heat soak.

Whether you're chasing lap times or just building it right the first time, this is one of those upgrades that actually makes a difference.
