Keep high-voltage spark moving to every cylinder with the Standard Ignition Distributor Rotor JR-172, a direct-fit application for the 1995-1998 Acura TL. Engine-level details are in the "Vehicles it fits" section. The rotor rides on the distributor shaft and spins inside the cap. It carries high voltage from the coil to each of the cap's spark plug terminals in firing order.
Signs a distributor rotor may need replacing include misfires, rough running, hesitation, and hard starting or a no-start. On inspection, look for a burned or eroded tip, cracks, or carbon tracking. If a worn rotor is the cause, this unit replaces it. Diagnose the ignition system first, because spark plugs, plug wires, the cap and the coil can cause similar symptoms. The rotor and distributor cap are commonly serviced together.

This part cross-references / interchanges with the following part numbers:
What does a distributor rotor do?
It sits on the distributor shaft and spins inside the cap. It carries high voltage from the coil to each spark plug terminal in the cap, so each cylinder receives spark in firing order.
Which vehicles does the Standard Ignition JR-172 fit?
JR-172 is listed for the 1995-1998 Acura TL. Engine-level fitment details are shown in the "Vehicles it fits" section.
What are the rotor's contact segments made of?
Standard Ignition uses solid brass segments in its distributor rotors for better conductivity and a higher-voltage spark to the plugs.
How does this rotor help against carbon tracking?
It uses a high-grade dielectric strength alkyd that resists dirt sticking to the surface, which helps reduce carbon tracking.
Should I replace the distributor cap at the same time?
The cap and rotor work together and are commonly replaced as a pair. If your cap shows cracks, worn terminals or carbon tracking, consider replacing it along with the rotor.
