The difference between NGK BPR5ES and BPR4ES is their individual terminal type. The terminal of BPR5ES is a removable nut-style one, and the BPR4ES has a fixed and solid terminal. Therefore, the BPR5ES has to be screwed to mount in its place. Removal terminals are flexible to use in any connection type.
