Monitoring oil temperature is critical for engine longevity, especially in high-end racing engines where oil breakdown can lead to catastrophic failure. The Longacre 43350 Oil Temperature Sender is the professional-grade replacement sensor designed specifically for use with Longacre 270-degree sweep electric temperature gauges.
Featuring a 1/2" NPT thread, this sender is designed to thread directly into engine blocks, oil pans, or remote oil filter adapters. Unlike standard automotive sensors, this unit is calibrated for the expanded "full sweep" of a racing gauge, providing the driver with granular, high-resolution data in the 100°F to 300°F range. Whether you are replacing a sensor damaged by track debris or plumbing a second engine, this genuine Longacre component ensures your data remains accurate and repeatable.
Key Features
-
Optimized for 270° Sweep Gauges: Specifically calibrated to match the resistance curve of Longacre’s full-sweep electric oil temperature gauges, ensuring the needle position is perfectly accurate across the entire scale.
-
Standard 1/2" NPT Fitment: Features the most common heavy-duty thread size for oil pans and engine galleries, providing a robust, leak-free mechanical seal without the need for fragile adapters.
-
Rapid Thermal Response: Engineered with a high-sensitivity internal thermistor that reacts instantly to temperature fluctuations, giving the driver real-time feedback on oil cooler efficiency and engine load.
-
Rugged Racing Construction: Built to withstand the extreme vibrations and thermal cycling of a racing environment. The brass housing is corrosion-resistant and designed for a long service life in harsh conditions.
-
Single-Terminal Connection: Utilizes a standard stud-and-nut electrical connection, making it compatible with existing Longacre wiring harnesses and easy to service in the pits.
