Spectra 4401-4704 Charge Air Cooler

Spectra 4401-4704 is a charge air cooler built to lower compressed air temperature after it exits the turbocharger and before it enters the engine. Cooler intake air supports more consistent combustion chamber performance and is a direct replacement choice for turbocharged vehicle applications.

Compatible With select turbocharged applications, including Ford F-250 Super Duty and Ford F-350 Super Duty fitments where this part number is specified. The Spectra 4401-4704 charge air cooler is also cross-referenced to Karlyn 5139 and Tuff Support 611376 for the same application.

Key Features

• Charge air cooler for turbocharged engine systems
• Reduces intake air temperature after turbo compression
• Supports denser air delivery to the engine
• OE-style replacement under Spectra part number 4401-4704
• Cross-reference part numbers: Karlyn 5139, Tuff Support 611376

How It Works

This intercooler-style component removes heat from compressed intake air before it reaches the engine. Lower charge-air temperature helps maintain more stable air density, which is important for turbo diesel and other boosted applications that rely on controlled intake temperatures. If you are sourcing a replacement charge air cooler for a Ford F-250 Super Duty or Ford F-350 Super Duty, verify the part number 4401-4704 against the original unit before ordering.

Common Issues It Can Address

• Reduced cooling efficiency in the charge air system
• Heat-soaked intake air after turbocharger operation
• Loss of intake air density under load
• Replacement need after damage from road debris or corrosion
• Fitment-specific service replacement for turbocharged Ford truck applications

Installation Notes

Confirm the original part number, mounting points, and inlet/outlet configuration before installation. Inspect connected charge-air plumbing, clamps, and seals for wear so the replacement cooler can perform correctly. For vehicle-specific service, match Spectra 4401-4704 to the exact application listed by the catalog for your Ford F-250 Super Duty or Ford F-350 Super Duty.
