Shop Peterbilt 379 Air Intake Pipes, Turbo Hoses & CAC Boots
Investing in high-quality aftermarket replacement parts like Charge Air Cooler (CAC) Clamps, Boots & Hoses for your Peterbilt 379 truck can help to maximize boost pressure and protect your engine.
As a professional truck driver, you know your charge air cooler (CAC) system does more than just cool air it keeps your engine performing at its best. Our line of aftermarket CAC clamps, boots, and hoses is built to help you maintain peak boost pressure, reduce downtime, and extend the life of your turbocharged diesel engine.
Whether you're an owner-operator, a fleet manager, or a semi-truck shop mechanic, these parts are essential to keeping your 379's airflow system sealed, secure, and running smooth.
Why Buy Quality CAC Replacement Parts?
- Prevent Boost Leaks: A single tear in a charge air cooler boot or a loose clamp can rob your engine of power. Our CAC clamps and turbo boots maintain a reliable seal, even under high RPMs and extreme heat.
- Protect the Turbo: Boost leaks force the turbo to work harder. Over time, this leads to premature failure. Lock down your system with T-bolt clamps, reinforced air to air boots, and heavy-duty CAC hoses.
- Boost Fuel Economy: Keeping your charge air system sealed helps your engine burn fuel more efficiently. That means more miles per gallon and fewer fuel stops.
- Improve Engine Reliability: With secure, leak-free connections, your Peterbilt 379 high performance charge air cooler can do its job delivering colder, denser air for maximum torque and horsepower.
- Cut Downtime: A blown boot or leaking CAC pipe can and will take your truck off the road. Reliable boot kits, coolant tubes, and clamps help prevent roadside headaches.
These parts are built for heavy use. From daily hauls to cross-country runs, our CAC components are designed to take the abuse. Choose from:
- Silicone coolant hoses with high heat resistance.
- Peterbilt 379 AC lines to integrate cooling system efficiency.
- Heater hoses for consistent cab comfort.
- Coolant tubes and pipe fittings for complete airflow and cooling integration.
- Mount-ready clamps to match your existing Peterbilt 379 air intake pipe setups.
We also carry hump hoses for tricky connections where flexibility is key especially when aligning offset or angled pipes in tight engine bays.

Frequently Asked Questions About Peterbilt 379 CAC Clamps, Boots & Hoses
What does "CAC" mean, and what do these parts do?
CAC stands for Charge Air Cooler, also known as the intercooler. The clamps, boots, and hoses in this category connect the turbocharger to the charge air cooler and then to the intake manifold, carrying pressurized air through the system. These components need to form a tight, leak-free seal to keep boost pressure where it belongs.
How do I know if my CAC boot or hose needs to be replaced?
Common signs include a noticeable loss of power or fuel economy, a hissing or whistling sound from the engine bay, visible cracking or dry rot on the rubber boot, or a check engine light related to low boost or turbo pressure. Physically inspecting the boots for soft spots, cracks, or separation from the clamps is the most reliable way to confirm a leak.
Are these clamps, boots, and hoses specific to certain engines in the Peterbilt 379?
Yes. The Peterbilt 379 was built with several different engine options over its production run, and CAC hose and boot shapes, diameters, and routing can vary between them. Always check the fitment details listed on each product page and compare against your truck's engine and chassis specs before ordering, since a boot that looks similar may not seal correctly on a different setup.
What material are the boots made from, and does it matter?
CAC boots are typically made from reinforced silicone or rubber compounds designed to handle heat and pressure cycling from the turbo system. Silicone boots generally hold up better to extreme temperatures and long-term flexing than standard rubber, which is worth considering if your truck runs long hours or in harsh conditions.
Do I need any special tools to install a new CAC clamp, boot, or hose?
Most installations only require basic hand tools such as a socket set or screwdriver to loosen and tighten the clamps. Before installing, make sure the mating surfaces on the pipes are clean and free of old sealant or debris, and tighten clamps evenly to manufacturer torque specs to avoid over-tightening, which can crack the boot, or under-tightening, which can cause boost leaks.
