Spectra 4401-4624 Intercooler

Spectra 4401-4624 Intercooler Overview

The Spectra 4401-4624 intercooler is a charge air cooler built to reduce turbocharged intake air temperature before it enters the engine. With an aluminum tube-and-fin core and plastic inlet tank material, it supports efficient airflow and heat transfer for select vehicle applications.

Compatible With select GM applications, including Buick Regal and Pontiac Grand Prix fitments, this intercooler is identified by part number 4401-4624 and cross-references Timken 222240 for the same application.

Key Features

• Aluminum core construction for effective heat exchange
• Tube-and-fin design for charge air cooling performance
• Single-row core layout
• Silver finish
• 100 mm inlet and 100 mm outlet sizing
• Plastic inlet tank material
• No cap included
• Core dimensions: 830 mm height, 161 mm length, 64 mm thickness

How It Works

This intercooler cools compressed air after it leaves the turbocharger and before it reaches the engine. Lower intake air temperature supports denser charge air entering the combustion chambers, which is important for maintaining consistent engine operation in turbocharged systems. The Spectra 4401-4624 is a direct-fit style charge air cooler for applications that use the listed inlet and outlet sizing.

Common Issues It Can Address

• High intake air temperatures in turbocharged operation
• Reduced charge air cooling efficiency from a damaged core
• Leaks at the intercooler assembly or tank connection points
• Restricted airflow through a bent or clogged cooler
• Loss of performance caused by heat-soaked charge air

Installation Notes

Verify inlet and outlet diameter, core dimensions, and mounting layout before installation. Inspect connected charge pipes, clamps, and seals for wear so the replacement intercooler can operate correctly. Confirm vehicle application by part number 4401-4624 and compare the original unit to the replacement before assembly. Fits select Buick Regal and Pontiac Grand Prix applications as listed by the catalog data.

Quality Assurance

Spectra manufactures this charge air cooler to meet the dimensional and functional requirements of the listed application. The aluminum core and tube-and-fin construction are specified to support consistent cooling performance in turbocharged intake systems.
