Product Overview

This high-quality Original Spark Plug CPR8EA-9 is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2015-2020) models.

The CPR8EA-9 spark plug generates the electrical spark needed to ignite the air-fuel mixture in the engine, driving the combustion process that powers the motorcycle. Over time, the central electrode erodes and carbon deposits build on the plug face, weakening the spark and causing rough idling, misfires, reduced fuel economy, and poor cold-start performance. This original CPR8EA-9 replacement restores reliable ignition and smooth engine performance to your NMAX 125.

Complete Part Guide

If the engine feels flat, hesitant, or less responsive than usual, it's often due to weak ignition. Replacing it with the aftermarket Yamaha NMAX125 Spark Plug CPR8EA-9 (Part Number: 94700-00415-00) for 2015-2020 restores a strong, consistent spark for smoother combustion and improved engine response. Engineered for fit and function, it matches factory specifications for direct installation. Built to handle everyday riding with dependable performance and stable ignition output. Available from Part Hive's London hub, with same-day UK dispatch on all orders before 1 PM.

We don't just look at the plug; we check how the engine behaves. On the NMAX-125, worn spark plugs reduce combustion quality, leading to rough running and lower efficiency. Riders often try quick fixes, but the issue stays. We remove the plug, inspect the electrode condition, and monitor engine response during testing. Once the spark is no longer consistent, we install a high-grade aftermarket Yamaha spark plug, engineered for fit and function. That restores proper ignition and keeps the engine performing as it should.
