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.
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.
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.
It also has triple gasket sealing features like the NGK BPR4ES, which virtually removes gas leakages past the shell.
