NGK Genuine BPR5ES Spark Plug

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 Spark plugs with projected tips can focus the spark further, thereby enabling the plug to swiftly ignite the air-fuel mixture and deliver an efficient performance. What happens if you run a hotter spark plug? 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.

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 BPR5ES and BPR6ES spark plugs are both manufactured by the famous NGK, a leading part manufacturer in the automotive industry. While the two spark plug models share a couple of similarities, there are still some notable differences between them in the similitude of BPR5ES Vs. BPR7ES. You will also find the solid copper core material in this spark plug, which provides superior heat conductivity, dissipation, and a wider heat range. Lastly, the triple seal feature of the NGK BPR4ES spark plug prevents any gas leakages. On the other hand, the NGK BPR5ES comes with cold-rolled threads that prevent damage to the cylinder head. 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. High quality NGK spark plug which is designed using the latest technology to give optimum performance over the Lawnmowers entire rev. rangeAnother 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. In the below guide, you will find out the difference between BPR4ES and BPR5ES in detail. Terminal Type 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. The BPR5ES spark plug is a standard plug size, having a thread diameter of 14mm as well as a thread reach of 19mm. The plug is compatible with a wide range of vehicle engines, including those with electronic ignition systems and others that use carburetors. Champion RC12YC and Denso W16EX-U are equivalent to BPR5ES. However, inasmuch as these spark plugs are equivalent with respect to their heat range and physical dimensions, they also have slight differences.

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. However, the reverse is the case for some spark plug brands (the higher the number, the hotter the plug). If you desire an NGK spark plug to be used in a high-performance vehicle engine, ensure to choose a colder spark plug that can handle the high RPM and loads. What is the proper gap for BPR5ES? Champion RN11YC4, Denso W16EPR-U, and Bosch WR7DC spark plugs are some of the close substitutes for the BPR6ES spark plug.

The NGK Standard Spark Plug is constructed from durable material that is corrosion and abrasion resistant. The spark plug insulators are made of 99 percent pure alumina silicate, allowing for longer insulator noses for reduced fouling. This spark plug features a triple gasket sealing process that eliminates fuel leakage. It also includes a solid copper core that provides superior heat dissipation and conductivity. This spark plug has resistor that is produced with a glass and carbon mixture, which is fired to ensure superior performance and durability. It has corrugated ribs that prevent flashover and cold rolled threads to inhibit damage to the cylinder head.

No.” The BPR5ES spark plug is designed with a lower heat range of 5 compared to the BPR6ES, which has 6; hence it may not be able to dissipate heat as efficiently as the BPR6ES.Therefore, it is crucial to hold onto the spark plug specifications recommended by your vehicle’s manufacturer to keep it running efficiently. Final Words 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.
