NTP YR123 Ignition Distributor Rotor Replacement

The NTP YR123 is a replacement ignition distributor rotor designed to restore reliable spark delivery in distributor-equipped ignition systems. This rotor cross-references the YEC part number YR123 and OEM part number 1910250020, making it a direct-fit replacement option for applicable vehicles.

How It Works:

The distributor rotor installs inside the distributor housing, beneath the distributor cap, on the end of the shaft driven by the camshaft. As the engine runs, the rotor spins and makes sequential contact between the ignition coil terminal and each individual spark plug wire terminal on the underside of the distributor cap, delivering high-voltage current to each spark plug at precisely the correct moment for combustion.

Key Features:

• Direct-fit replacement for original equipment distributor rotor
• Cross-references OEM part number 1910250020 and YEC part number YR123
• Manufactured to meet original design and operating specifications
• Restores proper spark timing and ignition system performance
• Made in Japan (YEC — Yamaguchi Electric Industry Co., Ltd.)

Distributor rotors are a wear item subject to heat, high voltage, and mechanical stress. A worn or cracked rotor can cause engine misfires, hard starting, rough idle, or an illuminated Check Engine light. Replacing the distributor rotor as part of a routine tune-up — typically every 50,000 miles or as symptoms appear — helps maintain a healthy ignition system. It is recommended to inspect and replace the distributor cap at the same time for optimal results.
