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? However, the NGK BPR5ES spark plug does not spark as hot as the NGK BPR4ES spark plug. A user said in a forum in Lawn Care Forum regarding this, I was working on my Ryobi pressure washer with Honda GCV190 the other day and had to read repair manual for it. According to the manual GCV 190 requires NGK bpr5es but in pressure washer applications it needs bpr6es. I removed my plug and came to find out it's bpr5es.

Typically, on NGK spark plugs, the higher the range number, the colder the spark plug, and vice versa. In other words, the lower the range number, the hotter the plug. Therefore, 8 is hotter than 9. 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.Mixing spark plug types is not a good idea as they are manufactured with different specifications and compatibility. Hence, if you combine different spark plug types in your vehicle’s engine, you may experience inconsistent performance and efficiency. Therefore, it is crucial to hold onto the spark plug specifications recommended by your vehicle’s manufacturer to keep it running efficiently. Final Words So, we can say that the NGK BPR5ES spark plug lasts longer compared to the NGK BPR4ES spark plug. Price 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.

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 On the other hand, the terminal of NGK BPR5ES is a nut-style type terminal. It is a standard spark plug that the connection is removed, unlike the fixed one. So, you need to screw the NGK BPR5ES spark plug to mount in its place.

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.

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? 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 Zowwie! That baby is running HOT. Agree that the glowing muffler is not likely to be a spark plug issue (at least by itself). The first thing I would suspect is an exhaust valve lash that is way too tight. Or, if the engine speed surges up and down under load, you know it is too lean. It could be a combination of the two. You don't usually see sheared flywheel keys on pressure washers, as there is not a spinning blade to hit things with, so I doubt it's that.

What is a substitute for BPR6ES?

If the gap (distance) between the center and side electrodes is too small, you will most likely experience a weak spark, thereby leading to poor engine performance. Does it matter which spark plug? If you run a hotter spark plug in your vehicle’s internal combustion engine, there’s a tendency to experience overheating. If this is the case, the electrodes in the spark plug may wear out faster. You may also experience pre-ignition issues.

In the below guide, you will find out the difference between BPR4ES and BPR5ES in detail. Terminal Type High quality NGK spark plug which is designed using the latest technology to give optimum performance over the Lawnmowers entire rev. range 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. Therefore, it would be best to use the BPR5ES for better performance, especially in a case where you’re battling a fouling issue.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 Champion RN11YC, Denso W16EPRU, Bosch WR8DC, WR9DC, Rocwood F5RTC, Oregon 77-314-1, O-LR17YC, LR17YC, Torch F5RTC. 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.
