Standard Ignition JP-18P Ignition Contact Set

Ignition Contact Set for Primary Ignition Service

Standard Ignition JP-18P is an ignition contact set built for primary ignition service in classic distributor systems. It is supplied as points and is pre-aligned and pre-adjusted to reduce setup time and help maintain proper switching.

Key Features

• Contents: points
• Pre-aligned and pre-adjusted for faster installation
• Lubricated felt pad helps reduce cam lobe wear on the distributor
• Ventilated tungsten contacts help run cooler and reduce erosion where available
• Copper-alloy shunt improves conductivity and resists breakage from arm flexing
• Standard Ignition JP-18P is backed by a manufacturer serving the automotive aftermarket since 1919

Detailed Description

The Standard Ignition JP-18P ignition contact set is a direct-fit service part for distributor-based ignition systems that use points. It is engineered to support consistent switching performance, with a lubricated felt pad to help protect the rubbing block and extend service life. The tungsten contact design and copper-alloy shunt are used to improve durability and electrical performance in primary ignition operation. This part cross-references A539 and CS378 for the same application. For technicians servicing older vehicles, JP-18P is a practical choice when replacing worn ignition points on applications such as Jeep and AMC models that use this style of distributor ignition.

What It Helps Fix

• Hard starting caused by worn or pitted points
• Misfire from inconsistent primary ignition switching
• Rough idle related to contact wear
• Ignition timing drift from deteriorated point surfaces
• Excess rubbing block wear in distributor service

Installation Notes and Tips

Inspect the distributor cam, rubbing block, condenser, and ignition coil before installation. Set point gap and dwell to the vehicle specification after installation, then verify timing. Clean the distributor base and contact surfaces before assembly to help maintain stable operation. Fits should be confirmed against the vehicle’s distributor application before ordering, especially on Jeep and AMC models using points ignition.
