Airtex 1R1343 RY132T Starter Relay 12V 4-Terminal Ignition Cut-Off Relay

The Airtex 1R1343 is a direct-fit replacement starter relay (also known as a starter cut-off relay) designed to restore reliable ignition system operation. Cross-referencing the popular RY132T specification, this 12-volt, 4-terminal relay is engineered to meet or exceed original equipment performance standards.

The starter relay acts as an electromagnetic switch in the ignition circuit, allowing a low-current signal from the ignition switch to control the high-current circuit that energizes the starter motor. A failed or degraded relay can result in a no-start condition, intermittent cranking, or a starter that remains engaged after the engine fires.

Key Features:

• 12-Volt operation — compatible with standard automotive electrical systems
• 4-terminal design — direct plug-in replacement for OE-style starter cut-off relays
• Functions as a starter relay, starter cut-off relay, and multi-purpose ignition relay
• Built to ISO/TS 16949:2002 quality standards for consistent performance
• Manufactured by Airtex Automotive Division, a trusted name in OE-replacement components

Cross-reference part number: RY132T. This relay is a straightforward drop-in replacement suitable for a wide range of domestic and import vehicle applications.
