## Overview

The NGK BPR6EIX Iridium IX spark plug leverages advanced iridium technology to deliver superior ignition performance, longer durability, and improved fuel efficiency. Designed for both older motorcycles and modern vehicles, it reduces misfires and enhances acceleration, making it a smart upgrade for enthusiasts and professionals seeking reliable, high-performance engine starts.

## Description

With the high-performance Iridium IX spark plug, NGK now makes advanced "Iridium" technology available for older motorcycles and vehicles! Because it is a precious metal, Iridium makes it possible to make the centre electrode of the spark plug significantly narrower. This has the advantage that the mixture can flow better between the centre electrode and the earth electrode, resulting in better ignition. Compared to standard spark plugs, the chance of a misfire is greatly reduced and fuel is optimally utilised. At the same time, iridium wears far more slowly, providing a longer service life than standard plugs despite the small diameter. Further advantages: Excellent acceleration values, optimised ignition behaviour, better and smoother engine operation and a longer service life - while at the same time providing lower fuel consumption. An investment that pays off! In motor sports as well as in daily use, iridium is a high-tech metal that provides absolute top performance. That's why more and more manufacturers are installing iridium spark plugs in their standard production models. When will you switch?

Review: Una buena bujia a un buen precio. Noto el arranque más enérgico incluso a patada.
Review: Iridium spark plugs help your power equipment start with one pull or crank all the time. I used the BPR6EIX for my champion 6500w geni and the results were apparent with the first start. I will probly switch all of the plugs in my power equipment for ease of starting.
