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. Although NGK BP6ES and BPR6ES spark plugs are manufactured by NGK, the two models come with some discrepancies like the case of BPR5ES 11 Vs. BPR5ES. The heat range is the main difference between the two spark plugs.

Generally, both the BPR5ES and the BPR6ES spark plugs are sold with a standard manufacturer’s warranty. However, the period and terms of the warranty will largely depend on the supplier in some cases. What Is The Difference Between NGK BPR5ES And BPR4ES? Therefore, it would be best to use the BPR5ES for better performance, especially in a case where you’re battling a fouling issue. These spark plugs are also designed with thread size, reach diameter, and capacity to deliver optimum engine performance and efficiency like their BPR6ES counterpart. You can consider one of them if you’re looking for a replacement for your BPR6ES. Is it OK to mix spark plug types? 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. Many vehicle owners use BPR5ES spark plugs to fight poor fuel economy issues, as well as acceleration and emissions problems.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.

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. range It does this thousands of times each minute. Over time spark plugs start to break down, resulting in a poor spark. A healthy engine needs good clean spark plugs. 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 600NGK 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. Champion RN11YC4, Denso W16EPR-U, and Bosch WR7DC spark plugs are some of the close substitutes for the BPR6ES spark plug. These slight differences can impact their performance and suitability for different vehicle engines. The following are some of the differences between BPR5ES and BPR6ES with respect to their metal property, insulator, copper core, triple seal, performance, pricing, and warranty. Metal

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. 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. 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. The plug also has a resistor built into the ceramic insulator that helps to minimize electromagnetic interference and noise. The BPR6ES high-quality materials and durable construction style provide exceptional performance and extended service life.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?
