Wells 4R1187 Distributor Rotor

The Wells 4R1187 Distributor Rotor is a precision-engineered ignition component designed to deliver reliable high-voltage current distribution in your vehicle's ignition system. As part of the distributor assembly, this rotor works in conjunction with the distributor cap to transfer electrical current from the ignition coil to the appropriate spark plug wire, ensuring proper engine timing and combustion.

Key Features:

• Constructed from high-grade dielectric strength polymer material that resists breakdown and arcing for extended service life
• Solid brass contact segment provides superior conductivity and resists pitting and erosion
• Stainless steel spring ensures positive contact with distributor cap brush while resisting corrosion
• Designed to meet or exceed OE specifications for form, fit, and function
• Manufactured by Wells Vehicle Electronics, a trusted leader in automotive electrical components for over 120 years

Regular replacement of the distributor rotor is essential for maintaining optimal engine performance. A worn or damaged rotor can cause misfires, rough idling, poor fuel economy, check engine light illumination, and difficulty starting. For best results and to prevent compatibility issues, the distributor cap and rotor should always be replaced together as a matched set.
