Katech LS Billet Oil Cooler Adapter

Katech LS Billet Oil Cooler Adapter

Katech-Engineered Billet Aluminum Adapter with Included -10 AN Connections

The Katech LS Billet Oil Cooler Adapter provides a compact connection point for adding or upgrading an external oil cooler on compatible LS engine applications. Engineered and manufactured by Katech, the adapter utilizes existing oil cooler connection provisions to accommodate -10 AN oil cooler lines.

The blue billet aluminum body features clearly labeled IN and OUT ports and laser-etched Katech branding. Two adapter fittings are included to connect compatible -10 AN oil cooler lines.

The compact design takes nearby wiring, surrounding components, and full-length header clearance into consideration. Verify clearance with your specific engine and header combination during installation.

Oil Temperature Sensor Compatibility: The Katech LS Billet Oil Cooler Adapter does not include an oil temperature sensor provision. Applications requiring a sensor at this location need an appropriate alternative arrangement.
