Spark plug NGK BR9ES 5722

Spark plug NGK BR9ES, NGK number 5722 from the name: 14 mm thread, a suppression resistor, a long 19 mm reach, heat rating 9 on the NGK scale.

• The NGK number 5722 — it is taken from the name and is the one to quote when you reorder
• The letter B in the code is a 14 mm thread; the letter R is the interference-suppression resistor
• The number 9 is the heat rating on the NGK scale: a higher number means a colder plug
• The letter E is the 19 mm reach — that is how far the plug goes into the head
• The same category also has the BR8ES 5422 — the same 19 mm reach, only the heat number is 8

We write only what we know. The photos are the same ones as on the neighbouring BR8ES product, and they show a "5422 BR8ES" box, not a BR9ES one. So the photo proves nothing here, and every figure is taken from the name alone; we are asking the maker. The NGK code tells you the thread diameter, the resistor, the heat rating and the reach, but it does not tell you which machine the plug is for — we will not derive that from the code and we do not write it. Before ordering, copy the marking off your old plug or measure its thread and write to us — we will check it before you order.
