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

NGK BPR5ES (7422) - Standard Spark Plug - Opie Oils

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.

BPR6ES Spark Plug 

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. 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. 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.

Does it matter which spark plug? 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. 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.Megane Petrol Saloon 2.0 i 1998cc 84KW 114HP F3R 750;F3R 751;F3R 752;F3R 791;F3R 796;F3R 797;F3R 798 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. 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? 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 The proper gap for the BPR5ES spark plug is 0.028 in – 0.030 in (0.70 mm – 0.80 mm). It is essential to state that the gap is a significant factor that determines the performance and efficiency of a spark plug.
