Adapter Set Engine Oil & Coolant Sensor Gauge

The ICT Billet Adapter Set Engine Oil & Coolant Sensor Gauge (part number 551156) is a precision aluminum fitting kit designed to integrate aftermarket oil pressure and coolant temperature sensors into GM LS-series engines. This straight adapter system consolidates dual gauge functionality into a single, factory-integrated installation point, eliminating the need for multiple aftermarket bungs or engine block modifications.

Constructed from lightweight aluminum and finished in natural (bare) material, the adapter maintains the thermal characteristics essential for accurate sensor readings on high-output LS platforms. The straight-fitting design ensures proper sensor alignment and eliminates flow restrictions that can compromise coolant circulation or oil pressure accuracy. LS-series engines—particularly in performance and racing applications—demand precise engine monitoring to prevent detonation, manage thermal stress, and optimize tuning parameters. This kit delivers the mounting infrastructure required for reliable real-time data without cutting or drilling into the block itself.

This adapter set is purpose-built for LS engine builders, performance tuners, and enthusiasts upgrading to digital or analog gauge clusters. Whether you're running a naturally aspirated, turbocharged, or supercharged LS platform, accurate oil pressure and coolant temperature monitoring is non-negotiable for engine longevity and safe operation. The compact 3.4 x 2.25 x 5.75-inch footprint fits seamlessly in tight engine bay configurations, and the aluminum construction resists corrosion when exposed to oil and coolant environments. Installation pairs seamlessly with popular LS performance sensor suites and aftermarket gauge systems commonly used in street, drag, and road-racing builds.
