CSF 6090 Intercooler

CSF 6090 Intercooler Overview

The CSF 6090 intercooler is an aluminum, OE-style tube and fin core unit built for charge-air cooling performance in turbocharged applications. With a 28 1/2-inch core length, 27-inch core width, and 2-inch core thickness, it is sized for direct replacement use where a factory-style intercooler is required.

Its 4-inch inlet and 4-inch outlet tubes support large-diameter charge-air routing, while the aluminum core and aluminum tanks provide a durable construction for demanding engine bay conditions. This CSF intercooler is a practical choice for BMW and Volkswagen applications that use this style of cooling layout, including vehicles commonly searched by model and part number, such as CSF 6090.

Key Features

• OE-style tube and fin core design
• Aluminum core construction
• Aluminum tank material
• Core dimensions: 28 1/2 in. length, 27 in. width, 2 in. thickness
• 4 in. inlet tube and 4 in. outlet tube
• Built for factory-style intercooler replacement applications

Detailed Description

CSF part number 6090 is an intercooler designed around an OEM-style tube and fin core layout, which helps maintain the original packaging and airflow approach used in many factory turbo systems. The aluminum core and aluminum end tanks are selected for a lightweight, corrosion-resistant construction, while the large 4-inch inlet and outlet tubes support high-volume charge-air flow. For shoppers comparing BMW intercooler and Volkswagen intercooler options, CSF 6090 is a direct-fit style replacement to evaluate against the original unit and common cross-reference numbers.

This part cross-references Spectra Premium 4401-2507 for the same application.

What It Helps Address

• Damaged or leaking factory intercooler core
• Cracked or fatigued aluminum tanks
• Restricted charge-air cooling from a deteriorated OE unit
• Boost pressure loss caused by intercooler failure
• Replacement needs for BMW and Volkswagen turbocharged cooling systems

Installation Notes and Tips

Verify core dimensions, inlet and outlet size, and mounting layout against the original intercooler before installation. Confirm hose routing and clamp fitment for the 4-inch inlet and outlet tubes, and inspect adjacent charge-air piping, seals, and brackets for wear before reassembly. Because fitment data is not provided here, confirm application by matching the OE part number and physical dimensions to your vehicle.

Quality Assurance

CSF manufactures this intercooler with an OE-style tube and fin core design and aluminum construction for replacement use in factory-style cooling systems. Part number 6090 is built to match the dimensional and connection requirements of the original intercooler layout.
