Product Details

The DU-2142 ignition contact set is designed around the needs of traditional distributor ignition systems. The lubricated felt pad helps maintain contact between the rubbing block and distributor cam, while the contact material and shunt construction support stable electrical performance. Standard Ignition DU-2142 is a direct-fit service part for restoring ignition switching in older vehicles that still use points.

This part cross-references DENSO Auto Parts 221-9161 for the same application.

Common Issues It Can Help Address

• Misfire from poor contact switching in the distributor
• Excessive rubbing block wear from dry cam lobes
• Weak ignition performance from damaged or fatigued point components
• Intermittent ignition operation caused by contact erosion or breakage

Installation Notes and Tips

Inspect the distributor cam, rubbing block, and condenser condition before installation. Set the point gap and dwell to the vehicle specification after installation, then verify timing and idle quality. Standard Ignition DU-2142 is intended for distributor-based primary ignition systems, so confirm the original point-style setup before ordering.
