It also has triple gasket sealing features like the NGK BPR4ES, which virtually removes gas leakages past the shell. Other features of the NGK BPR5ES like the copper core and trivalent metal plating are the same as the NGK BPR4ES. However, we can say that the NGK BPR4ES spark plug has more features than the NGK BPR5ES spark plug. Durability Champion RN11YC4, Denso W16EPR-U, and Bosch WR7DC spark plugs are some of the close substitutes for the BPR6ES spark plug. In the below guide, you will find out the difference between BPR4ES and BPR5ES in detail. Terminal Type 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? 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?

NGK spark plugs are renowned spark plugs around the world for their quality. Though there are several series of NGK spark plugs in the market, in this article, we will only discuss the differences between the NGK BPR4ES Vs BPR5ES. Stay tuned to know more. NGK BPR4ES Vs BPR5ES: Differentiation At A Glance Key DifferencesThe 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. The NGK BPR4ES spark plug comes with trivalent metal plating that provides superior anti-seizing and anti-corrosion properties. It also has corrugated ribs, which prevent flashover. This spark plug has a pure alumina silicate ceramic insulator, which provides better heat transfer and superior strength. 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.

Many vehicle owners use BPR5ES spark plugs to fight poor fuel economy issues, as well as acceleration and emissions problems.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? 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.

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. Therefore, it would be best to get a complete match according to the required specifications when replacing your car’s old or faulty spark plugs. What spark plug is hotter, 8 or 9?The dimension of the NGK BPR4ES spark plug is 3.43 x 1.69 x 0.94 inches. Its weight is ‎4.2 ounces. On the other hand, the dimension of the NGK BPR5ES spark plug is ‎3.3 x 1 x 0.8 inches. Its weight is ‎0.32 ounces. So, when differentiating between the spark plug BPR4ES vs BPR5ES, if you are looking for a lightweight option, then go for the NGK BPR5ES spark plug. Features 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.
