CAC Hoses

Charge air cooler hoses connect the turbo, intercooler and intake on boosted engines, and the factory rubber versions are a common failure point on diesels and turbo gas engines. This collection covers the Vibrant Performance silicone CAC hoses, reinforced to hold their shape under high boost and engine bay heat. They replace cracked or swollen OEM boots and are a common upgrade for tuned trucks running more boost than stock.

Install tip

Clean oil residue off the pipes before installing and use T-bolt clamps to keep the hose from blowing off.

Why do CAC hoses fail? Heat, oil from the PCV system and boost pressure break down rubber. Silicone handles all three better.

How to Choose

Measure the outside diameter of the pipes you are joining and choose a coupler with a matching inside diameter. Straight couplers join two pipes in line, elbows turn the path, hump hoses absorb engine movement and reducers join two different sizes. Reinforced silicone holds its shape under boost and heat where rubber hose would balloon or crack.

Common Questions

What clamps should I use with silicone couplers?

T-bolt clamps give the most even clamping force and are the best choice on boosted joints. Bead the pipe ends so the coupler cannot blow off.

Can silicone couplers be used on coolant lines?

Silicone works well with coolant, but check the inside diameter and temperature needs for your application.
