Upgrade Your Air Intake System with New CAC Clamps, Boots or Hoses
If your Peterbilt 567 or 579 wonât hold boost, start with the CAC system. CAC clamps, boots, and hoses move cooled, pressurized air from the turbo to the engine. When they seal tight, your truck runs strong and efficient.
A leaking CAC boot dumps boost fast. Power drops. Throttle response slows. Fuel burn climbs just to keep speed. That poor air balance creates soot, which loads the DPF and increases the risk of a derate.
Oil is the biggest threat to CAC boots. Turbo oil mist softens silicone over time. Boots swell. They lose shape. Then they blow under load. Replacing oil-soaked boots early prevents roadside breakdowns.
Clamps matter. Weak clamps let hoses shift under boost. That causes leaks and can pull dirty air into the intake. Grit inside the engine causes permanent damage. Heavy-duty CAC clamps keep everything locked in place.
Warning Signs that You Need a Replacement
You may hear a hiss or whistle.
You may see oil on the boots.
You may notice lower boost on the dash.
Replacing CAC clamps, boots, and hoses is a smart preventative fix. It costs less than a tow. It saves downtime.
This selection of Peterbilt 567 and 579 CAC clamps, boots, and hoses is built for commercial use. They restore power. They protect the emissions system. They keep your truck moving and making money.
