Product Description

This aircraft ignition component is a Slick 4371 series magneto configured for four‑cylinder engines and used to provide spark for engine ignition. It is designed for left‑hand rotation with an impulse feature for installation on compatible Lycoming engines in the O‑235, O‑320, O‑360, IO‑320E1B, IO‑320E2B, AEIO‑320E1B, AEIO‑320E2B, AEIO‑360B1C6, and H1A families, where it serves as one of the primary engine magnetos.

0 1. Overview

The 4371 configuration belongs to the 4300 series of aircraft magnetos and serves as a direct replacement for earlier 4200 series units in the same application range, while incorporating an updated case and bearings. In this configuration the magneto includes an impulse mechanism and uses a 3/4‑20 spark plug connector interface matched to the intended Lycoming engine installations. The magneto family is constructed as a lightweight design at approximately 3‑3/4 pounds, reducing mass compared to older ignition units in the same role and maintaining a rebuildable design for continued service. Within its supported applications the 4371 model is paired with the M2508 harness reference for a complete ignition system match on the specified Lycoming engine list.
