Product Overview

This high-quality Original Spark Plug Cap Assy is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2020) models.

The spark plug cap assembly connects the high-tension ignition lead to the spark plug, ensuring that the electrical pulse from the ignition coil is delivered reliably to the plug to generate the combustion spark. Over time, the cap's internal contact and suppressor can deteriorate, causing a poor electrical connection that results in misfires, rough idling, intermittent loss of power, and difficulty starting. This original replacement restores a secure, low-resistance connection between the ignition lead and the spark plug, ensuring clean and reliable ignition performance.

Complete Part Guide

When the connection between the ignition coil and spark plug becomes loose or inconsistent, the engine can’t fire properly. Fitting the original Yamaha NMAX125 Spark Plug Cap Assembly (Part Number: 2DP-H2370-10) for 2015–2020 restores a secure, stable transfer of voltage for smooth and reliable combustion. Manufactured to Yamaha’s original specification, it ensures accurate fitment and dependable operation. That consistent spark makes a noticeable difference in everyday riding. Available from Part Hive's London hub, with same-day UK dispatch on all orders before 1 PM.

Ignition problems aren’t always the plug itself. On the NMAX-125, we often trace weak spark back to the plug cap. If the connection isn’t tight or has worn internally, current flow drops and combustion suffers. Riders often overlook it and try other fixes first. We inspect the cap, check its grip on the plug, and test electrical transfer. Once it’s not delivering properly, we install the correct original Yamaha spark plug cap assembly, restoring a clean connection and bringing the engine back to consistent, reliable running.
