When it comes to durability, the NGK BPR5ES spark plug wins the race. The NGK BPR5ES spark plug is made for longer life and supreme performance. The NGK BPR4ES sparks hotter to aid it to start when the tractor is cold. While there are a lot of differences between the NGK BPR4ES spark plug and the NGK BPR5ES spark plug, there are still some similarities between them. The table below will show you those similarities. Major Similarities

Therefore, it is crucial to hold onto the spark plug specifications recommended by your vehicle’s manufacturer to keep it running efficiently. Final Words 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 So, we can say that the NGK BPR5ES spark plug lasts longer compared to the NGK BPR4ES spark plug. Price 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. It means the 5 heat range level in the NGK BPR5ES keeps it colder compared to the BPR4ES spark plug which has the highest 4th thermal stage.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. Since they can dissipate a lot of heat efficiently, most high-performance car owners use BPR6ES spark plugs to manage the high level of heat generated by their engines to prevent overheating.

However, it is always better to consult your car’s manufacturer’s manual to ascertain the spark plugs’ specifications for your internal combustion engine; otherwise, ask a professional auto mechanic. What does the P stand for in BPR6ES? In other words, the BPR6ES spark plug is more suitable in high-performance engines that generate a lot of heat due to its ability to prevent overheating. So, if your car’s engine is built to run with BPR6ES spark plugs and you replace them with BPR5ES, you may experience fouling, misfiring, overheating, etc.The P in BPR6ES stands for “projected insulator or projected tip.” This type of spark plug has an extended ceramic insulator tip that protrudes further than regular insulator tips in most spark plugs. BPR5ES spark plug is used to combat vehicle engine issues that are fuel-related. The spark plug provides faster ignition, as well as enhanced fuel efficiency, smoother acceleration, and minimal emissions. In the below guide, you will find out the difference between BPR4ES and BPR5ES in detail. Terminal Type NGK BPR5ES and BPR4ES spark plugs are both manufactured by NGK. The two spark plugs are built with several similarities in many ways. However, they also have a couple of vital differences just like BP5ES Vs. BPR5ES.

The BP6ES spark plug is built with a colder heat range compared to its BPR6ES counterpart, which means that the former is designed with the capacity to dissipate more heat and prevent engine overheating.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. Typically, using the spark plug recommended by your vehicle’s manufacturer for your engine is best. If you are not sure of the spark plug to use, ensure to consult your owner’s manual or an expert auto technician. FAQs What spark plug is the same as BPR5ES? Though both come from the same brand NGK, what is the difference between BPR4ES and BPR5ES? The major difference between the NGK BPR5ES and NGK BPR4ES series of the spark plug is in their particular terminal type. There are many more differences, including dimension, features, durability, and price. Nevertheless, the final choice is yours. We suggest you consider the aspects discussed in this NGK BPR4ES vs BPR5ES article before selecting one between them. 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.
