Reference
B7HS (from the title) — no R in the code, and the digit is the heat range
Range
Yellow Box, NGK’s standard range following original equipment (maker’s bullet)
Threads
Cold-rolled with a corrosion-resistant coating, stated to dissipate heat well (maker’s bullet)
Operation
Stated to run smoothly at low and high engine speeds (maker’s bullet)

Quantity
1 plug (maker’s bullet)

EAN
0087295151105
  • Publishes the thread treatment, which is what stops a plug seizing in an alloy head
  • The clearest contrast in this family: same maker, no resistor, one heat range apart
  • Not a resistor plug — that is a specification, not a saving

Best for: A machine whose manual names B7HS — and not a substitute for one that names BR8HSA.

What the seller commits to paper

B7HS, Yellow Box — the standard range, stated to follow original equipment. Cold-rolled threads with a corrosion-resistant coating, stated to dissipate heat well. Smooth running at low and high engine speeds. One plug.

Read the code against its neighbour

BR8HSA, in this same family, and B7HS, here.

No R. This is not a resistor plug. A resistor suppresses ignition interference; an engine whose manual specifies one wants one.

7 against 8. A different heat range — in NGK’s system, a lower number is a hotter plug.

Two differences, in a code that differs by one letter and one digit, on plugs that sit side by side on the same shelf at nearly the same price. This is why a plug is bought against a manual and never by eye.

The thread detail

Cold-rolled with a corrosion-resistant coating. A plug lives threaded into a hot alloy cylinder head for thousands of miles, and the thing that goes wrong is it seizing and pulling the head’s threads out on removal. Publishing the thread treatment is publishing the answer to that.

The rows this seller leaves empty

Thread diameter, reach and gap. The reference carries them in NGK’s own catalogue; the listing carries the reference.
