Peterbilt 330/335/337 Charge Air Coolers

Heavy-Duty Intercoolers for Peterbilt 330/335/337 Truck Models

We stock a wide array of replacement intercoolers for the Peterbilt 330/335/337 model truck. The charge air cooler (CAC) is responsible for cooling down the hot air generated by the turbocharger before it enters the engine. A damaged CAC can lead to worse-case-scenarios like: turbo failure, clogged DPF (diesel particulate filter), worn-out pistons/rings, and cracked manifolds that result in exhaust leaks. If you're seeing symptoms like: a high-pitched hissing sound when the turbo cycles up, a drop in horsepower and torque, black smoke from the exhaust, rising exhaust gas temps seen from your pyrometer gauge, and a drop in MPG. Thankfully, we stock made-to-fit replacements that quickly ship to your specified address so you can get back on the road faster. You can find CAC kits with durable silicone hoses, heavy-duty T-bolt clamps, and mount bushings for a secure, leak-free installation.
