This water/air intercooler pump is designed for circulating water in water/air intercoolers.

Unlike other bilge pump-based solutions available, this pump is designed by Bosch and Ford specifically for water/air applications.

This pump is Bosch part number 0 392 022 002 and is used in many of the supercharged Mustang Cobras and supercharged Mercedes.

This is an OEM pump. It ships with no documentation. Please check below for pump specifications from Bosch; these are the most detailed specifications available:

This information is directly from Bosch. Unit conversion shows that this pump flows 317 GPH; any seller who advertises differently is incorrect.

VERY IMPORTANT! We ship these pumps with a wiring harness adaptor that will give you positive and negative wires to connect the pump electrically. Most sellers of this pump just ship it with the socket and you have to find your own adaptor. The adaptor can cost up to $20 plus shipping by itself!

The Bosch Cobra Water to Air Intercooler Pump is designed for a 16 gauge wire, which this part has. Most connectors you will find being sold for this pump are fuel injector connectors with 18 or 20 gauge wire which may result in poor pump performance, voltage drop, or dangerously hot wires.

These Rule 401FC pumps are designed for livewell/baitwell/bilge applications but their high flow rate and low cost makes them ideal for use as water to air intercooler pumps.

• Must be mounted at the low point in the system – these pumps push water but they will not pull it.
• Must be mounted after the water in your system is cooled (after radiator or icebox) – excessive heat may result in premature pump failure.
• Pump operates on 12V-14V DC.
• Flow rate: 500 GPH.
• Designed for use with room temperature water, however we have tested these pumps long term with 130° antifreeze/coolant with excellent results.
• Designed with a minimum 1500-hour service life in mind, these pumps come with a 3 year warranty direct from Rule/ITT. However, use with high temperature water and/or antifreeze/coolant may void this warranty.

Pump is brand new and will be shipped in retail packaging.
