NGK Genuine BP6ES Spark Plug - silver/white

Product Information

Both spark plugs are designed with an alumina ceramic insulator that enables them to withstand high temperatures and helps to provide good electrical insulation. However, the BPR6ES insulator is slightly longer than that of the BPR5ES spark plug. Copper Core TheBPR5ES spark plugis one of NGK’s popular spark plug models. Being a key player in the automotive industry, NGK produces some of the best spark plugs for a wide range of vehicles and motorcycles. A - Since they early 80's fuel injection systems have been designed by manufacturers to be fitted with resistor spark plugs. Fitting non resistor plugs in a resistor application can cause damage expensive components, affect overall performance and increase fuel consumption. A spark plug produces a high intensity electrical discharge (the spark) inside the combustion chamber, igniting your fuel to keep the engine firing.

Another notable difference between the BPR5ES and BPR4ES spark plugs is their electrode design. The BPR5ES plug has a U-groove electrode that helps to enhance ignition and minimize fouling. On the other hand, the BPR4ES is built with a standard electrode design. With older leads the conductor insulation is subject to continual heat and eventually breaks down. Old connectors can have resistance that increases anywhere up to 1350ohms which is getting into the heading for trouble zone. I fail then to understand at all why Bosch would recommend using a resistor plug in a W126 application - you are just asking for trouble.

Can I Use A BPR5ES Instead Of A BPR6ES

The BPR5ES is built with a smaller electrode than its BPR6ES counterpart. This makes the BPR5ES deliver a hotter spark and better ignition. However, the smaller electrode can also result in faster wear and tear on the spark plug. Insulator Mixing spark plug types is not a good idea as they are manufactured with different specifications and compatibility. Hence, if you combine different spark plug types in your vehicle’s engine, you may experience inconsistent performance and efficiency. This listing is for one plug so if you need more then simply add that number of items to your basket. Suitable for any points type ignition system, our Powerspark Electronic Ignition Electronic Kits, and other electronic ignition systems.

This review differentiates between BPR5ES Vs. BPR6ES spark plugs, including their pros and cons. Therefore, while NGK stands as a reputable brand generally, you need the best model for optimal engine performance. High quality NGK spark plug which is designed using the latest technology to give optimum performance over the Lawnmowers entire rev. range BERU Ultra X and Ultra X Platinum ? the spark plugs for x-tremely high demands. | Federal-Mogul Global Aftermarket The spark plug has a tapered cut ground electrode that helps to minimize quenching and enhance flame kernel growth for better engine performance. Like BPR5ES, the spark plug also has a thread diameter and a thread reach of 14mm and 19mm, respectively, which makes it fit for a wide range of engine types and models. Firstly, the heat range is one of the main differences between the BPR5ES and BPR4ES spark plugs. While the BPR5ES spark plug has a heat range of 5, the BPR4ES spark plug is built with a heat range of 4. In other words, the BPR5ES can dissipate more heat than its BPR4ES counterpart.Undoubtedly, NGK manufactures some of the best spark plugs in the automotive industry. Nevertheless, their various spark plug models are designed for use in different applications. The BPR6ES spark plug is designed with a copper core electrode. This feature provides excellent conductivity and heat transferability for reliable engine ignition and efficient combustion. ago under guidance of a local Mercedes Authorised Repair/service Centre the owner "who is also an old school Mercedes fanatic" told me the best now plug to run in our engines is "Beru Ultra-X UX79" Part # 0 002 335 600
