Overview
A copper core and nickel electrodes make up this NGK BPR6ES, which the listing calls dependable for cars, marine and small engines. It is sold as a vehicle specific fit.
The reason to buy is a conventional plug with its gap and thread already stated. Heat range and reach are left out, and the warranty detail is thin.
Who it's for
Cars, trucks and small engines that specify this plug. Anyone seeking a longer-life tip should check iridium options.
Pros and cons
- Gap stated in the listing
- Stated service range
- Heat range not given
- Reach not listed
Performance notes
Nickel electrodes wear steadily, so the service range is modest. A copper core pulls heat away from the tip, and the stated gap helps with setting the plug straight from the box.
